1. removed BaseTimerLibLocalApic from MdePkg and Nt32TimerLib from EdkNt32Pkg.
2. added BaseTimerlibNullTemplate in MdePkg and SecPeiDxeTimerLibCpu in MdePkg. 3. modified the related spd and fpd files git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2347 6f19259b-4bc3-4df7-8a09-765794883524
