mb/google/hatch/var/dratini: Add FP enable
Add FP enable/disable based on SKU ID for Dratini. This is meant to resolve a UMA issue with Dratini 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:354769653 BUG=b:200825114 TEST=Flash to Dratini, test FP. Disable test SKU, flash on Dratini, test FP. To test, run `ectool --name=cros_fp version` in the shell When enabled, the fpmcu fw version should be displayed. When disabled, an error should be displayed because the fpmcu is inaccessible.
