powerpc/86xx: Add power management support for MPC8610HPCD boards

Browse source 
This patch adds needed nodes and properties to support suspend/resume
on the MPC8610HPCD boards.

There is a dedicated switch (SW9) that is used to wake up the boards.
By default the SW9 button is routed to IRQ8, but could be re-routed
(via PIXIS) to sreset.

With 'no_console_suspend' kernel command line argument specified, the
board is also able to wakeup upon serial port input.

@ -20,12 +20,16 @@ Required properities:
- compatible : should be "fsl,fpga-pixis".
- reg : should contain the address and the length of the FPPGA register
set.
- interrupt-parent: should specify phandle for the interrupt controller.
- interrupts : should specify event (wakeup) IRQ.
Example (MPC8610HPCD):
board-control@e8000000 {
compatible = "fsl,fpga-pixis";
reg = <0xe8000000 32>;
interrupt-parent = <&mpic>;
interrupts = <8 8>;
