gpio: wcd934x: Fix shift-out-of-bounds error
bit-mask for pins 0 to 4 is BIT(0) to BIT(4) however we ended up with BIT(n - 1)
which is not right, and this was caught by below usban check
UBSAN: shift-out-of-bounds in drivers/gpio/gpio-wcd934x.c:34:14
Fixes: 59c324683400 ("gpio: wcd934x: Add support to wcd934x gpio controller")
