Clean up and document PMU config options
No functional changes, just documenting and renaming.
All boards which use the PMU must provide pmu_board_init(). This was
already true - except that Daisy's pmu_board_init() was implemented as
part of pmu_init() instead of its code living in board.c; I've moved
the code there now.
