This reverts commit 50213f97bc. This sets
JSONPLAT during compilation and doesn't disable it during cmake's configure
process which is done by jenkins. This means that mraa_init_platform_json never
gets define since it's under an #ifndef
This fixes PWM on the GT platform. The code was only used on gen1 galileo and
is rarely used because it's the only platform in mraa that supports 2 functions
on the same pin without any time of advanced function pointer being called
(gen2/edison). GT however has kernel side muxing which causes the gpio to be
initialised meaning the PWM channel is never set to active as it's activated
after the GPIO is opened and the GPIO keeps precendence

Unfortunately GT has alot of i2c buses, the second lot of designware buses can
turn up after the i915 i2c buses but since they all have the same name, we do a
dumb check to see if they are 5/6 or 9/10. Hopefully future kernel/firmware
will let us do something smarter.

Added standard context validity check, another check for a replace function
and corrected a return statement to fit our standard code style.

Mock platform allows one to use mraa without having any real HW.
This commit makes necessary foundational changes and implements
GPIO functionality as well as adds respective tests.

IIO mount matrix is supported in kernel version 4.6.
Change mraa_iio_get_mount_matrix to take in one more parameter
‘mount matrix sysfs entry name’, because different sensor driver
may expose different mount matrix sysfs entry.
Following link explain the mount matrix usage and sysfs entry:

As described in issue #91, on Edison setting 0% duty doesn't
disable the PWM on a pin completely.
Therefore we add a couple of Edison-specific _pre functions
and an internal PWM state variable, which we use to toggle PWM
enabled/disabled based on what duty is set for the pin.
Closes#91.

Make better use of unsigned/signed ints, signed ints are preffered unless there
is a good reason not to.

Go through channel array after getting byte mapping to correctly map channel
location. Doing it at the same time as mapping the indexes is unreliable
depending on filename etc...

Partly rollsback f2c4d95c15 which stopped
mraa_i2c_init from switching i2c bus silently. If you don't want this to
happen, you need to use mraa_i2c_init_raw. Closes#497.

This fixes previous broken commit because dev is not defined before
_internal_init but since fp is taken during internal init we need to know the
channel number. This does not affect the internal override API.
