mb/google/guybrush/var/guybrush: Update GPIO configuration
Some of the GPIOs are either re-purposed for different use-cases or are
unused in upcoming board phase (board version 2). Update the GPIO
configuration accordingly. Here are the GPIOs that are updated:
GPIO Board Id 1 Board Id 2
=============================================
GPIO31 TP183 EN_SPKR
GPIO69 EN_SPKR SD_AUX_REST_L
GPIO70 SD_AUX_RESET_L Unused TP27
GPIO74 RAM_ID_CHAN_SEL Unused TP49
BUG=b:189327557, b:188542649, b:188542497
TEST=Build Guybrush mainboard. Verify Audio is audible and SD card is
detected fine in Board ID 1.
