While the NUC5i7RYB doesn't provide any built-in IO, this change will at least allow it to be used with a subplatform from IDEs that filter out unknown devices (e.g. Intel XDK).

Currently, mraa_init is called when loading libmraa. This commit
adds similar functionality to call mraa_deinit when unloading
libmraa. This is a nice-to-have since it makes identifying other
memory leaks easier.

GPIO and I2C functions of some PINs are not possible
with default BIOS configuration. Current documentation
wrongly shows that the PINs can work as both GPIO and I2C.
This patch fixes this issue and also updated pin conf for

The earlier patches did not fix the following issues.
1) gpio number used for ISH I2C 0 and I2C 1 were not correct
2) gpio number used in ISH I2C 1 and I2C 2 were not correct
3) ISH UART 0 gpio numbers were wrong

MRAA is using gpio 484, 483, 485 and 486 as ISH UART1.
But J13 expansion connector doesn't expose ISH UART1,
instead it exposes ISH UART0 as per dev kit hardware guide.
This patch fixes this descrpency and renames the UART and
also enables the GPIO usage.

The GPIOs are not mapped correctly in MRAA for tuchuk board.
This patch corrects the GPIO maps and the PIN assignments.
Note:
1) There are nothing called I2S(x)SDO and I2S(x)SDI available over breakout
pins, the usage is commented now.
2) There is nothing called SPP0FS3, is now commented, what we have is SPP1FS3.
3) I2C1SDA available twise 15 and 71. PIN 71 as per gpio used should be renamed as ISHI2C0SDA
4) I2C1SCL available twise 17 and 73. PIN 73 as per gpio used should be renamed as ISHI2C0SCL
5) UART1TX available twise 22 and 74. PIN 74 as per gpio used is ISHUART1TXD
and is not available in breakout.
6) UART1RX available twise 24 and 76. PIN 76 as per gpio used is ISHUART1RXD
and is not available in breakout.
7) I2C2SDA available twise 19 and 75. PIN 75 as per gpio used is ISHI2C1SDA
and is not available in breakout pins
8) I2C2SCL available twise 21 and 77. PIN 75 as per gpio used is ISHI2C1SCL
and is not available in breakout pins
9) PIN 78 UART1RT as per GPIO used is ISHUART1RT and is not available in breakout pins
10) PIN 80 UART1CT as per GPIO is ISHUART1CT and is not available in breakout pins

The gpio pins numbers aren't just matching the physical pin numbers...
on some distros like raspbian, with a kernel explicitly setting the
base to 0, it works, but for kernels using the first free slot it
doesn't (see gpiochip_find_base() in kernel's gpiolib.c).
To get the proper gpio pin value, we thus need to find the base for
the corresponding gpiochip. For the raspberry pi, we search for the
chip with a label containing 'bcm2835'.

While some distributions have a modified /proc/cpuinfo including
the board revision for raspberry pi, most distributions don't
have this.
In order to guess the raspberry pi version in such cases, use
the /proc/device-tree/compatible content as a fallback solution.
The values expected from this file have been taken from
upstream kernel documentation:

Like the beaglebone, the phyBOARD-Wega also got an am335x.
So I merged the four mmap-functions for gpio_context and some
identical defines in a separate header and c-file.
The new platform support-files are based on beaglebone-files.
The documentation of phyBOARD-Wega is still in process,
but for now there are enough informations.
At this time it is possible to use GPIO-Pins and Uart0
(tested via python with mraa). The code for using SPI, I2C and
PWM is also still in process and not tested yet.
