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 Change-Id: Ib4f2bd0f68debd4e97ccaab9e1d8a873dc4e4d9f Signed-off-by: Brandon Breitenstein <brandon.breitenstein@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/48814 Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Caveh Jalali <caveh@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
