mb/google/ocelot/var/ocelot: disable HDA GPIOs by default

Browse source 
Configure GPP_F10, GPP_F11, GPP_F12, GPP_F13, GPP_F16, and GPP_F17
as no-connects by default.  These GPIOs will be enabled in
fw_config.c if they are needed.

BUG=b:447648103
TEST='emerge-ocelot coreboot chromeos-bootimage`, flash and boot ocelot
and verify the AUDIO_ALC721_SNDW still works.
