staging: mt7621-gpio: fix masks for gpio pin
BIT macro is being used to get mask for gpio's pin
which is retrieved using 'hwirq' from struct irq_data.
The problem here is that 'hwirq' can be as large as 95,
and 1UL << 95 is unlikely to work well. Instead of using
BIT macro use a new PIN_MASK macro which takes into account
pin and WIDTH of the bank in order to make a proper mask for
the gpio pin. Also 'd->hwirq' has been replaced by 'pin' in
some places because there was a 'pin' variable in changed
functions with the proper value. This improves readability.
