[PATCH 2/7] ASoC: rt5677: clean up gpiolib callbacks

[Vladimir Zapolskiy <vz@xxxxxxxxx>]

The main intention of the change is to remove bitwise operations on
GPIO level value as a preceding change before updating gpiolib
callbacks to utilize bool type representing a GPIO level. Usage of
generic over GPIO[1-5] macros allows to remove calculations with magic
numbers.

No functional change.
