rockchip: Implement a panic handler that will reboot the system 

The current Rockchip platform code retains the "common" default panic
handler which simply hangs the system (until the watchdog kicks in, if
enabled). This is usually not a great user experience.

This patch implements a Rockchip-specific panic handler that calls the
platform's reboot implementation to reset the system.
