Alexander Sverdlin 6521f6a195 ARM: AM33xx: PRM: Implement REBOOT_COLD
Historically AM33xx performed warm software reset even though requested
(and default) was REBOOT_COLD. Reflect the de-facto default mode in
/sys/kernel/reboot/mode correctly and implement the real REBOOT_COLD
(if configured explicitly).
