ARM: 6101/1: nomadik-gpio: don't enable in set_type
On this peripheral, setting the trigger type enables the interrupt, and
the current set_type() implementation unconditionally enables the
interrupt, even if it is called when the interrupt is disabled. Fix
set_type() to:
- if the interrupt is disabled, defer the actual trigger setting to
when it is unmasked
- if the interrupt is enabled, change the type immediately by clearing
the old type and then re-enabling with the new type.
