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