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.

Since google_chromeec_cbi_get_board_version and google_chromeec_cbi_get_fw_config both call cbi_get_unit32 and return 0 as success, non-zero as failure. Let's add more readability for the false condition.

GPIO_89 was marked as EN_DEV_BEEP_L in pre-v3.6 schematics, but it was
never really used on any of the zork variants. Starting with v3.6,
GPIO_89 is left unused in schematics.
This change configures GPIO_89 as PAD_NC in baseboard GPIO
table. Since EN_DEV_BEEP_L still needs to be driven high to allow
speakers to work, GPIO_89 is configured as PAD_GPO driven high on
pre-v3.6 schematics.

This change adds support for touchscreen power control using:
* GPIO_90 for trembyle based boards
* GPIO_32 for dalboz based boards
By default, baseboard tables configure these GPIOs as PAD_GPO driven
low and override trees expose these pads as enable_gpio to be used by
ACPI power resource.
In order to support pre-v3.6 boards, override tables configure these
pads as PAD_NC and drop the enable_gpio setting from device tree based
on board version.

v3.6 of reference schematics have switched the polarity of reset
signal to touchscreen controller from active high to active low. This
change updates the default configuration in baseboard gpio tables to
set the reset GPIO to output low and override tables in variants to set the
reset GPIO to output high. Additionally, devicetree by default exposes
ACTIVE_LOW configuration for reset GPIO. In order to support pre-v3.6
boards, reset GPIO is updated to ACTIVE_HIGH based on board version.
