google/gru: Stop mucking with unused I2S0 pins in codec config
Due to a schematic error, our code was written to configure more I2S0
pins than are actually used. We're also pinmuxing the whole bank of pins
over to the I2S controller even though we don't need them all. Restrict
the GPIO initialization and pinmuxing to the pins we really need so the
other ones can be correctly used as SKU ID pins on Scarlet.
Also, move the "audio" IO voltage domain selection to the other such
selections in the bootblock, since that covers two whole banks of GPIOs
and there's no guarantee that they're all used for audio (and thus not
needed before ramstage).
BUG=b:69373077
TEST=Booted Scarlet, confirmed correct SKU ID (7) was detected on rev2.
