hw/arm: Add basic power management to raspi.

This is just enough to make reboot and poweroff work. Works for
linux, u-boot, and the arm trusted firmware. Not tested, but should
work for plan9, and bare-metal/hobby OSes, since they seem to generally
do what linux does for reset.

The watchdog timer functionality is not yet implemented.
