mb/google/zork: Add FP enable for Morphius
Add FP enable/disable based on SKU ID for Morphius. This is meant
to resolve a UMA issue with Morphius devices that had the FPMCU
populated on non-fp devices. Since the FPMCU is present, and the
firmware enables the power GPIO's based on variant, not SKU, the
devices were reporting data on fingerprint errantly.
BUG=b:258040377
TEST=Flash to Morphius, test FP.
Disable test SKU, flash on Morphius, test FP.
