MIPS: SEAD3: Use generic restart-poweroff driver
Remove the custom platform code to restart when instructed to power off,
instead relying upon the generic restart-poweroff driver probed via DT
to do the same thing.
Remove also the halt implementation, which is incorrect. The generic
MIPS version will hang the system as halt should.
