drivers: gpio: use of_match_ptr() and ACPI_PTR() macros

The of_match_ptr(foo) macro evaluates to foo, only if
CONFIG_OF is set, otherwise to NULL. Same does ACPI_PTR with
CONFIG_ACPI. That's very helpful for drivers that can be used
with or without oftree / acpi.

Even though most of the drivers touched here probably don't
actually need that, it's also nice for consistency to make it
the de-facto standard and change all drivers to use the
of_match_ptr() and ACPI_PTR() macros.

A nice side effect: in some situations, when compiled w/o
CONFIG_OF/CONFIG_ACPI, the corresponding match tables could
automatically become unreferenced and optimized-away by the
compiler, w/o explicitly cluttering the code w/ ifdef's.
