picoxcell: support for Picochip picoxcell devices

Picochip picoXcell device tree bindings.

========================================

Required root node properties:

    - compatible:

	- "picochip,pc7302-pc3x3" : PC7302 development board with PC3X3 device.

	- "picochip,pc7302-pc3x2" : PC7302 development board with PC3X2 device.

	- "picochip,pc3x3" : picoXcell PC3X3 device based board.

	- "picochip,pc3x2" : picoXcell PC3X2 device based board.

Timers required properties:

    - compatible = "picochip,pc3x2-timer"

    - interrupts : The single IRQ line for the timer.

    - clock-freq : The frequency in HZ of the timer.

    - reg : The register bank for the timer.

Note: two timers are required - one for the scheduler clock and one for the

event tick/NOHZ.

VIC required properties:

    - compatible = "arm,pl192-vic".

    - interrupt-controller.

    - reg : The register bank for the device.

    - #interrupt-cells : Must be 1.

	  This enables support for NVIDIA Tegra based systems (Tegra APX,

	  Tegra 6xx and Tegra 2 series).

	  This enables support for systems based on the Picochip picoXcell

	  family of Femtocell devices.  The picoxcell support requires device tree

	  for all boards.
