- FT4222 GPIO ISR implementation was specific to C/C++ and ignored
language binding support. This is now fixed via adv_func updates.
- GPIO ISR code has been refactored to reduce i2c traffic when using
I/O expanders
- Added support for built-in FT4222 GPIO interrupts

This fix only affects USBPLAT=ON which would cause mraa_init to return
uninitialised if we had detected a platform. Whilst the initialisation had
actually been done correctly the results would be that platform_name was
unfilled and no iio initialisation was done

Somewhere between kernel v3.18 and v4.4 the output of /proc/cpuinfo
stopped showing the board model. This confused MRAA when running on
HiKey. Eventually we want to do a better job of getting the kernel to
express hardware information to userspace, but in the mean time fix the
test so that MRAA will work on HiKey.

mraa_intel_edison_misc_spi is specific to the Arduino board.
Call it only when miniboard is not 1.

Move mraa_intel_edison_misc_spi to mraa_intel_edison_spi_init_pre.
There is no point in initializing SPI if it's not used.
Set the direction of GPIO 214 (TRI_STATE_ALL) only if it's not set
to *out*.

The pinout for the Low Speed Expansion on the MinnowBoard
Turbot is the same as the MinnowBoard MAX A2 desgin, with
the exception of pin 26. Pin 26 was changed to provide an MCLK
reference clock for I2S.
In addition, the D2 LED is now under GPIO control.
Add support for these changes.

Switch to using calloc on all calls to malloc where the memory isn't
initialized. For things like the mraa_board_t, not allocating all to zero
causes issues such as with the sub_platform member, where if that's not zero
mraa_get_platform_type will try to dereference a random memory location for the
sub_platform->platform_name, which can result in segmentation faults and other
issues.
Note that in some places where immediately after the malloc call is a copy
operation, there is no need for calloc, as all the memory gets overwritten
anyways, but in cases where there may or may not be memory written to (such as
in mraa_file_contains, with reading from a file), even though in most cases the
memory is overwritten, it could be the case that the read operation does
nothing, but the memory still has non-zero values, by virtue of the fact it
wasn't overwritten.

Since on most 3rd party breakout boards the i2c bus exposed is 1 and not 6, it
makes more sense to have that as the default i2c bus

By default, CMake assumes both a C and C++ compiler are required.
This is not needed for mraa because it only provides C++ header
files. Note that if using SWIG you need one and if using node.js 3+ you'll need
a C++11 compiler
