mainboard/google/herobrine: Add configuration for SD card detect pin

Without this configuration, even though there is no SD card it shows as
SD card is present and host controller waits for card to respond.

BUG=b:182963902
TEST=Validated on qualcomm sc7280 development board with SD card and
without SD card, make sure if SD card not present then host controller
should not wait for card to respond.
