mb/google/poppy/variants/nocturne: configure the FPMCU interface
The FPMCU is using the standard cros-ec-spi interface on GSPI1.
Configure the GPIOs controlling the MCU too.
We need to be able to wake from S3 on the MCU interrupt, re-configure
GPE0 DW0 to point to GPP_C bank.
BRANCH=poppy
BUG=b:79666174
TEST=exercise the cros_ec interface, e.g. 'ectool --name=cros_fp version',
verify the MKBP events by doing 'ectool --name=cros_fp fpmode fingerup'
then 'ectool --name=cros_fp waitevent 5 10000', toggle the other GPIOs
with the flash_fp_mcu script.
