[PATCH] SecurityPkg: Get default value from same source for TCG2_PHYSICAL_PRESENCE_FLAGS_VARIABLE

["Maggie Chu" <maggie.chu@intel.com>]

https://bugzilla.tianocore.org/show_bug.cgi?id=2713
In current code, If TCG2_PHYSICAL_PRESENCE_FLAGS_VARIABLE variable is not exist,
code will get default value from two places.
This fix is to make the default value comes from the PCD
gEfiSecurityPkgTokenSpaceGuid.PcdTcg2PhysicalPresenceFlags
