TscTimerLib in PerformancePkg is a BASE type library, which should be used by any module type.
But its constructor uses the global variable mTscFrequency to store frequency, which doesn't work on XIP PEIM. Split it to two LIBs for PEI and DXE separately. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11312 6f19259b-4bc3-4df7-8a09-765794883524
