pinmux: Add support for ARM V2M Beetle Initialization
This patch adds the support for the board pinmux initialization on ARM V2M Beetle. The GPIO controllers 2 and 3 are reserved and therefore neither exposed nor configured by this driver.

/**

* @brief Pinmux driver for ARM V2M Beetle Board
|
||||||
|
*
|
||||||
|
* The ARM V2M Beetle Board has 4 GPIO controllers. These controllers
|
||||||
|
* are responsible for pin muxing, input/output, pull-up, etc.
|
||||||
|
*
|
||||||
|
* The GPIO controllers 2 and 3 are reserved and therefore not exposed by
|
||||||
|
* this driver.
|
||||||
|
*
|
||||||
|
* All GPIO controller exposed pins are exposed via the following sequence of
|
||||||
|
* pin numbers:
|
||||||
|
* Pins 0 - 15 are for GPIO0
|
||||||
|
* Pins 16 - 31 are for GPIO1
|
||||||
|
*
|
||||||
|
* For the exposed GPIO controllers ARM V2M Beetle Board follows the Arduino
|
||||||
|
* compliant pin out.
