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.

The following APIs are only used for getting the line information from
kernel by opening the gpiochip independently and they fails to close
the file descriptor when done:
1. mraa_get_line_info_by_chip_number()
2. mraa_get_line_info_by_chip_name()
3. mraa_get_line_info_by_chip_label()
This will create issue if these API consumers like mraa_gpio_read_dir(),
mraa_gpio_mode(), mraa_gpio_chardev_dir() gets called in a loop. The
system will run out of file descriptor after some time.
Fix this issue by closing the opened file descriptors before freeing
the cinfo struct.

Move the chardev enablement inside the platform check.
Some boards might not have the chardev mapping yet.

The flag used for checking the kernel owned gpio line is GPIOLINE_FLAG_KERNEL.
Hence use that instead of GPIOLINE_FLAG_IS_OUT.
Flag used for checking the open source gpio line is GPIOLINE_FLAG_OPEN_SOURCE.
Hence use that instead of GPIOHANDLE_REQUEST_OPEN_SOURCE, which should be
only used when requesting lines.

As of now both Dragonboard410c and Hikey boards run latest LTS kernel.
Hence, adding chardev support for those.

This commit includes a set of small fixes flushed out from the google
unit tests.
* Fixed missing implementations of mraa_get_*_count methods.
* Fix for NULL string
* Fix for MOCK platform C++ define.
* Switched (void) -> () function definitions for consistency.

Remove some _multiple functions and replace with generic function that
does both. Some general cleanup and will move more interrnal mraa
functions to use the _mraa prefix

SPI_IOC_RD_MAX_SPEED_HZ is often incorrect and too low (RPI, UP2, galileo g1 at
least). Likely this is because driver writers are too concious of possible
issues or because they don't have the final hardware. Because of this we now
will only LOG_NOTICE on exceeding SPI_IOC_RD_MAX_SPEED_HZ and try keep going
anyways. This effectively will put the burden of not exceeding
SPI_IOC_RD_MAX_SPEED_HZ on our users.

Pinmap field value is an OS pin number, not mraa pin index,
so make the function return the proper one.
Fixes#817.

This patch adds support for using on board LED through sysfs.
Commonly available LED parameters are supported.

This commit adds a MRAA platform for the UP Squared board, EVT3 revision.
It handles the relevant FPGA configuration updates when using MRAA to
change pin modes or toggle GPIO directions.
