Vlv2TbltDevicePkg: Remove DxeTcg2PhysicalPresenceLibNull
https://bugzilla.tianocore.org/show_bug.cgi?id=908
The following commit that to use Tcg2 instead of TrEE breaks the
build of Vlv2TbltDevicePkg\Library\DxeTcg2PhysicalPresenceLibNull
9461604e14 (diff-c85873f3649e35873a11936ace983807)
The correct fix is to remove the DxeTcg2PhysicalPresenceLibNull
library instance and update library mappings in DSC files.
