gpio: deprecate gpio pin callback enable and disable API

Browse source 
These have been replaced by the appropriate call to
gpio_pin_interrupt_configure().  While the disable function could be
implemented using the new functionality, the enable function cannot
because the interrupt mode is not available.  Consequently we cannot
replace these with equivalent functionality using the legacy API.

Clean up the internal implementation by removing the inaccessible
port-based enable/disable feature, leaving the pin-based capability in
place.
