mainboard/volteer: Configure UsbTcPortEn value
The default value is not sufficient to correctly configure the Type-C
ports as it has all ports disabled by default. On Volteer ports 0
and 1 are enabled so setting this value to 0x3 and correctly
keeping the IomPortPadCfg values at 0 for ports that have a
retimer and ports that are not configured. These values were set
to 0x90000000 to avoid s0ix issues which arose from the UsbTcPortEn
value being incorrect.
BUG=b:159151238
BRANCH=firmware-volteer-13672.B
TEST=Built image for Voxel and verified that s0ix cycles complete
without any issues
