mb/google/volteer: Make use of fw_config_is_provisioned()
In cases when a volteer device is unprovisioned, the safest thing to do
for GPIOs that will normally be used for audio codec buses is to leave
them disabled (configured as PAD_CFG_NC). This patch adds support for
that.
BUG=none
TEST=add debug print to new if branch; remove fw_config from CBI and
see print on console
