mb/google/brya/var/brya0: add HPS as generic I2C peripheral
Some brya0 units have HPS fitted and connected to PCH I2C2, rather than
a user-facing camera.
Because HPS uses I2C address 0x51, which may conflict with the
user-facing camera EEPROM, introduce a new fw_config bit to indicate
whether HPS is present.
