mb/google/brya: Configure H21 as GPO and A17 as low
As per the schematics, UFC has on card oscillator so we donot need
H21 in NF1 that is IMGCLKOUT
H21 is used to enable this oscialltor so configuring it as 1
A17 is configured as high while _ON method is called by driver and
it is configured as low when _OFF method is called by driver.
Hence coreboot should configure it as low on boot.
