MAINTAINERS: add a keyword entry for the GPIO subsystem

Every now and then - despite being clearly documented as deprecated -
the legacy GPIO API is being used in some new drivers in the kernel. Add
a keyword pattern matching the unwanted functions so that I get Cc'ed
anytime they're being used and get the chance to object.
