OvmfPkg: drop PcdPciDisableBusEnumeration from the AmdSev platform

With the Xen-dependent PcdSetBoolS() call removed from
OvmfPkg/PlatformPei, the "AmdSevX64.dsc" platform never writes
"PcdPciDisableBusEnumeration". This means we don't need a dynamic default
for the PCD in the DSC file; it could be declared Fixed-at-Build.

However, because the PCD's default value in "MdeModulePkg.dec" is FALSE,
remove the (same-value) platform default altogether.
