gpio: generic: fix signedness bug found by cppcheck
cppcheck reports this:
(style) int result is returned as long value. If the return
value is long to avoid loss of information, then you have
loss of information.
This can be fixed with (1UL << pin) but that is the same
as using <linux/bitops.h> that already use 1UL so take
this approach.
