This patch adds a function to query UART settings in an unintrusive way.
It can be used using a uart index or a devpath and it strives to just
read out the settings without affecting the state of the UART.

This patch probably changes no functionality.
Before this patch the return value 0 was used for invalid baudrates in
uint2speed, but this is not a proper speed_t constant.
Instead the constant B0 is returned now, since on x86 and arm linux
architectures B0 is defined as 0.

This patch has no changes in function. It fixes three style issues
to be more readable and in line to the rest of the codebase:
- return types are declared on a separate line
- reversal of Yoda conditionals
- initialize for loop variable inside loop declaration
- Fix styling of pwm lookup doxygen

Return length of read bytes rather than 0 on success.
MRAA calls I2C_RDWR ioctl which returns number of bytes read.
PIO is yet to implement that API so currently does I2C_SMBUS
ioctl instead, which returns 0 in case of success.

Peripheral Manager provides mutual exclusion between pins
multiple functionalities. This feature in MRAA is redundant for
this platform.
Once the API to retrieve pin functionality from PIO is available
use it to update each pins capabilities.

The Native PIO API provides both the libraries and headers for use with
the Android Things Peripheralanager client. This commit removes these
from the MRAA repo in favor of the FindAndroidThings.cmake provided by
the Native PIO API.

Updated the java CMakeLists file to set the JAVA_INCLUDE_PATH for
Android Things. The JAVA SWIG wrapper will require the jni.h from the
Android NDK.

Use the cmake module provided by AndroidThings for setting libs/hdrs
instead of the hard-coded path to the AndroidThings library. This
requires adding a path to CMAKE_MODULE_PATH which contains
FindAndroidThings.cmake.

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.
