mb/ocp/deltalake: Use VPD data to configure FSP UPD at romstage
Read VPD variable 'fsp_log_enable' to decide enabling FSP log or not.
With VPD_RW_THEN_RO, VPD_RW takes precedence over VPD_RO, and
would be set to enabled if both places cannot find it.
Tested=On OCP Delta Lake, use vpd to create and set fsp_log_enable
and verified the results are expected.
