[PATCH v2] MIPS: Alchemy: fix up residual devboard poweroff/reboot code.

[Manuel Lauss <manuel.lauss@googlemail.com>]

Clean out stray unused board_reset() calls in pb1x boards,
the pb1000 is different from the rest and gets private methods.

(Cleanup after 32fd6901a6d8d19f94e4de6be4e4b552ab078620)
