Can't we just keep bit 18 out of the function mask? The bootloader
should already have made sure all pins have bit 18 set (and bit 19 set
to correct values after ROM mucked them up, see advisory 2.1.88), so
all that needs to be done is avoid touching them.

Are the power savings from disabling unnecessary inputs significant
enough to spend any headache on it?
