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).

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
I2C 1 and 2 to disable GPIO functionality.

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
This patch fixes this issue and also update the doc.

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
BIOS used is 193

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.

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.
