cbi: Introduce CONFIG_CBI_GPIO
For the boards where SKU_ID/BRD_ID comes from the strapping pins on EC,
this new config enables AP to ask EC for those hardware configs using
the CBI host command `EC_CMD_GET_CROS_BOARD_INFO`.
BRANCH=None
BUG=b:186264627
TEST=make buildall -j
TEST=Enabled CONFIG_CBI_GPIO for lazor and manually verified with
`ectool cbi get`.
