Karthikeyan Ramasubramanian 1b7dac1bd0 mb/google/guybrush: Setup EC_IN_RW GPIO and export to payload
EC_IN_RW_OD signal is routed from Google Security Chip to GPIO_91 in the
upcoming hardware build. The existing SD_EX_PRSNT signal is dropped in
the upcoming hardware build because SD7 support is dropped. Export the
EC_IN_RW GPIO for use by payload.

BUG=None
TEST=Build and boot to OS in Guybrush. Ensure that the device can boot
successfully in both recovery and normal mode.
