mb/google/zork: Init fingerprint GPIOs for boot vs resume
Add a function that initializes GPIOs based on the sleep type that
the system is coming back from. This allows initialization of the
fingerprint GPIOs which need to be handled differently between wake
from S3 and boot from S5.
On initial boot, the state of the FP sensor could be either
enabled or disabled. Because of this, on boot, we power off
the sensor for >200ms, to reset its state, then power it back on.
In suspend/resume, the fingerprint sensor should remain powered
the entire time.
If fingerprint is disabled on the trembyle-based board, set the pins
to no-connect. Dalboz doesn't have fingerprint and the GPIOS are
configured differently due to the FT5 chip having fewer GPIOS than
FP5, so nothing needs to be initialized there.
There were also a couple of trivial comment clean ups regarding the
FPMCU GPIOS.
