The OvmfXen platform specifies the dynamic access method for "PcdPciDisableBusEnumeration" needlessly. After the DSC file sets the PCD to TRUE by default, the InitializeXen() function in XenPlatformPei superfluously sets the PCD to TRUE again. There are no other writes to the PCD in the platform. Make the PCD Fixed-At-Build, and remove the access (in fact, the whole InitializeXen() function) from XenPlatformPei.
