power/common: Add board specific API for 5V control
Some boards need different mechanisms to enable/disable the 5V rail
that's not simply setting the PP5000_EN GPIO. This commit adds a new
board specific API to control the 5V rail. If a board needs something
more complex, they should define `board_power_5v_enable`.
BUG=b:149794574
BRANCH=None
TEST=Add definition for waddledoo, build and flash, verify that
sub-board 5V is turn on as well.
