Subject: [edk2-devel] [edk2-platforms][PATCH v1 1/1] MinPlatformPkg: Fix build errors in SmmVariableWriteLib

From: Michael Kubacki <michael.kubacki@microsoft.com>

Commit `b71f2bd` introduced a couple build errors in VariableWritelib. This change adds the SMM Services Table (`gSmst`) and MM Services Table (`gMmst`) calls needed to register the protocol notify in the Traditional and Standalone MM services constructors.
