OvmfPkg/PlatformPei: Skip various items for S3 resume
We will not be running DXE on S3 resume, so we don't need to do these initialization items: * Reserve EMU Variable memory range * Declare Firmware volumes * Add memory HOBs v5: * Move MiscInitialization back to running on S3 resume Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15295 6f19259b-4bc3-4df7-8a09-765794883524
