power: Refactor Makefile rules
Move the power/ rules into drivers/power to avoid clutter in the Makefile
and drivers/Makefile files.
We must select SPL_POWER if SPL_POWER_DOMAIN is used, since the two are
currently independent and boards do not necessarily enable SPL_POWER.
Add a TPL_POWER as well, as that is used by one board.
