mainboard/google/zoombini/variants/meowth: enable PCH_FP_PWR_EN
Turn on the load switch to the FP MCU at startup, so the kernel can
detect it and use it.
The load switch enable pin is connected to the GPP_A11 PCH pin (aka
PCH_FP_PWR_EN).
BRANCH=none
BUG=b:71986991
TEST=on Meowth, see the kernel detecting a cros_fp device at startup:
[ 2.133456] cros-ec-spi spi-PRP0001:00: Fingerprint MCU detected.
[ 2.157420] cros-ec-spi spi-PRP0001:00: Chrome EC device registered
