BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1961 Enhance Ppin code to enable and unlock for TRUE State, and disable and lock for FALSE State. Note: enable and lock could not be set both. According to SDM, once Enable_PPIN is set, attempt to write 1 to LockOut will cause #GP, and writing 1 to LockOut is permitted only if Enable_PPIN is clear.
