mb/google/guybrush: Make GPIO_69 default for SD_AUX_RESET_L 

In CL:3248796 GPIO_5 was made the default for SD_AUX_RESET_L. No variant
is actually using GPIO_5 for SD_AUX_RESET_L. Making GPIO_69 the default
and only overriding to GPIO_70 for guybrush bid==1.

BUG=b:202992077
BRANCH=None
TEST=Build and boot guybrush, SD card works
