I have another driver coming soon which will not depend on OF_GPIO. It
does however depend on OF. Its for a class of boards which have a
microcontroller controlling the main power supply, and sending an
character over a UART port is used to turn the board power off.

There might also be some legacy drivers which could be moved here
which don't depend on OF at all.

So i would prefer to keep POWER_RESET generic.
