This fixes the problem of detecting if pins 74-77 are available for gpio/spi use. These pins were sown to be used by the emmc, but actually used by the sound pcm. If the sound PCM is disabled and the emmc is enabled the pinse can now be used. mraa-gpio list output Pins 74-77
73 GPIO115: GPIO
74 GPIO113: GPIO SPI
75 GPIO111: GPIO SPI
76 GPIO112: GPIO SPI
77 GPIO110: GPIO SPI
to build:
1. clone repo
2. sudo apt-get install build-essential python-dev cmake automake libpcre3 libpcre3-dev byacc flex swig3.0
3. cd mraa, mkdir build, cd build
4. cmake -D CMAKE_INSTALL_PREFIX=/usr ..
5. make
6. sudo make install
This has been verified to work on BBGW, and BBBW with 9.0-9.5 with emmc enabled and PCM aduio turned off. It is so nice to have control of these pins when running with out an SD card.

Add onboard LED support for Dragonboard410c. There are 4 user LEDs and
two LEDs for BT and WLAN.

1. Add support for initializing onboard LEDs based on board definition.
Maximum LED count has been set to 12.
2. Introduce mraa_led_init_raw API for initializing LEDs based on
function name. This API can be used by platforms which doesn't have mapping
in board definition.

Multiple changes necessary to enable this. The main goal is to build
and run the C++ ioinit unit tests (which require c++11)
* Updated mraa required CMake version to 2.8.11 (this is needed for
the target_xxx_xxx CMake syntax.
* Added function for adding the c++11 flag give a CMake target.
* Updated unit tests for range of CMake versions (tested on 2.8.11,
3.8.2, 3.9.6, and 3.12.0).
* Added C++ unit test file (more needed here).)

This commit adds Ultra96, one of the Consumer Edition boards of the
96Boards family.
Ultra96 is an Arm-based, Xilinx Zynq UltraScale+ MPSoC development board.
This board runs petalinux distribution on the ARM core and integrates
Xilinx programmable logic (PL) UltraScale architecture in a single fabric.
This board supports standard peripherals defined by 96Boards CE
Specification. Since it ships with >4.8 kernel, only chardev mapping
is supported for accessing GPIO.
More information about this board can be found in 96Boards product
page: https://www.96boards.org/product/ultra96/

Since peripheral manager does not build in the IIO source, ifdef's were
added around the initio functionality for IIO.
IMO this is an ugly fix, but I don't see a better way since the
PERIPHERALMAN architecture is qualified throughout the CMake and source
with ifdef's.

This commit limits which tests run on which ARCH to allow all tests to
pass on CI.
* Qualify the FTDI tests with (FTDI4222 AND USBPLAT)
* Qualify the IO init tests with (DETECTED_ARCH == "MOCK")
* Renamed all unit tests to start with 'test_unit_' to facilitate
grouping with tab completion (or any other type of sorting)
* Updated docker targets with new unit test target name

For all subplaform pins, save the subplatform index as dev->pin and the
actual platform index as dev->phy_pin.
Example:
pin 515 (subplatform pin 3)
dev->pin = 515
dev->phy_pin = 515 - 512 = 3
In this way, methods which get a mraa_gpio_context have a means
to tell whether the pin is on a subplatform or not.

Updates to make the FT4222 platform extender more usable.
Previous implementation opened libft4222.so and loaded symbols as
needed. This implementation removes dynamic loading of libft4222 in
favor of creating a new shared libary which links against libft4222.so.
The dynamic loading is now done in mraa.c. One C method is exposed in
libmraa-platform-ft4222.so for finding/initializing an FT4222:
mraa_platform_t mraa_usb_platform_extender(mraa_board_t* board);
Mraa.c attempts to open this platform library and calls the
mraa_usb_platform_extender method. If an ftdi4222 is connected, the
user gets added IO from the extender. If no FT4222 device is connected,
continue as normal.
* Create a new platform library for the FT4222
* Expose only 1 C method from the library -
mraa_usb_platform_extender
* libmraa-platform-ft4222.so contains CXX code (as well as previous
C code). All *allocs have been removed in favor of global
C++ stl containers.
* Previously, the FT4222 would only initialize correctly if 2 ftdi
devices existed. Now, initialize FT4222 devices based on the
device id.
* Many fixes for various problems with the FT4222
* Added unit test for platform extender (minimal functionality w/o hw)
* Updated to FindFtd4222.cmake module to handle standard arguments
* Removed CMAKE_C_FLAGS addition of -DFTDID2XX and -DFTDI4222 since
these are NOT used anywhere in source.
* Building the FTDI4222 shim requires libft4222.h which requires
ftd2xx.h. Updated CMakeLists.txt to require both when building
the shim.

Unfortunately the device_path char* is dynamically allocated
and #defined and const char *'ed depending on how each platform provided the
uart device paths which makes cleaning it up more complicated.

If numDevs is not == 2, the previous code would fail. If numDevs > 2
(example 1 ft2xx device connected and 1 ft4222 device in mode 3) then
the code would not initialize the FT4222 and give an error that the mode
must be 0 or 3.
Updated source to find the first index of a ft4222 device. Initialize
it as I2C. If another device of the same id exists, then initialize it
as GPIO.
Added more syslog messages for debugging.

Add support for Hikey960 board from HiSilicon based on their Kirin960 SoC.
Peripherals supported:
1. GPIO
2. UART
3. I2C
For GPIO only Chardev interface has been added since this board only supports
>=4.15 kernel and using legacy sysfs interface is highly discouraged.
