mb/volteer: Set IomTypeCPortPadCfg default to 0x09000000
Temporary workaround for S0ix issues related to FSP's handling of 0 value.
When IomTypeCPortPadCfg is 0 FSP completely skips any flow related to this
value which seems to be causing issues with s0ix.
This is still being debugged and a final solution will be made when available
BUG=b:159151238
TEST=flash image with workaround to volteer and verify that s0ix
cycles correctly.
