This adds the PWM resources to the STMPE MFD driver, so that
it can properly grab and use them.

ChangeLog: split this patch off from the PWM driver and sent
separately. This can be merged separately too so we need no
criss-cross between MFD and PWM anymore, Lee: this one is for
you if it looks all right, excess newlines are gone too.
