[PATCH 5/7] ASoC: wm5100: remove bitwise operations involving GPIO level value

[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 to represent GPIO level.

No functional change.
