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.
