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.

Add pin commands. Old mraa_setup_mux_mapped style is used for other boards
(pincmd = PINCMD_UNDEFINED) where pincmds are not defined.Remove useless
pullup_enable code, Galileo Gen2: review all pin mux and add commands Galileo
Gen2: remove doubled functionality: mraa_intel_galileo_gen2_i2c_init_pre and
mraa_intel_galileo_gen2_uart_init_pre. Galileo Gen2: fix "Invalid AIO pin
specified - do you have an ADC?" error. Galileo Gen2: pullup/pulldown
resistors are disabled during UART/GPIO/SPI/I2C/UIO initialization. Use
mraa_gpio_mode to enable resistors.

This is a re-design of commit 0041801. mraa_lang_func_t structure has been
added (similar in design to mraa_adv_func_t) that points to JNI functions
implemented in src/java/mraajni.c. Functions are set by libmraajava.so,
see wrapper entry in src/java/mraajava.i. As gpio.c now uses these
functions, language specific #ifdef code has been removed as JNI code
is only called if functions are defined (i.e. not NULL)

libmraajava.so was statically linking to mraa object files causing
duplicate mraa platform instances if a UPM Java module was also loaded.
JNI functionality has been moved into src/java/mraajni.c. JVM object is
now set when JVM is loaded; see updates to src/java/mraajava.i.
This was necessary as the JVM object cannot be directly referenced from
mraa as it will not be available when building C/C++ examples.

Every 96Boards baseboard uses the same expansion connector, but the
current 96Boards initialization code assigns the SoC specific GPIO
numbers instead of being consistent across all boards. Change the code
to assign 96Boards GPIO-A through GPIO-L to MRAA GPIOs 23-34.
v2: Create info for all the LS connector pins, not just the GPIO pins.
This gives us room to describe other pins in the future.

- FT4222 GPIO ISR implementation was specific to C/C++ and ignored
language binding support. This is now fixed via adv_func updates.

Turbot is the same as the MinnowBoard MAX A2 desgin, with

In addition, the D2 LED is now under GPIO control.

This patch adds support to 96boards. 96boards is an open platform
specification. This spec strandardizes the pins on the external
connectors like Low speed and High speed. Given these pins are standard
across multiple boards, I think adding a generic 96boards made sense to
me.
The idea behind adding this generic board file is to make mraa work on
most of the 96boards with minimal changes to board support in libmraa.
This patch adds support to the LS expansion connector which has got 12
gpio pins + 2 i2c + 1 spi and 2 uarts.
For now I have added Dragaon board DB401c support as part of this patch
and is tested.
More info about board @ https://www.96boards.org/products/ce/dragonboard410c/
Long term plan is to get all this configuration from the /sys and
populate the board specifics dynamically, which is bit easy with
96boards specs in-place.

This is an attempt to make the mraa work on wide boards with minimal
board setup.
Most of the arm boards with latest kernel have pinmux already setup by
the driver and its really not necessary for mraa to check each pin and
icheck if the pinmux is required or not. Having this flag would cut lot
of code in board support and its possible to add some generic board
support which can make use of mraa easily.
Without this patch each board support has to have pins setup in there
bus structure.
