XenTimerDxe is a local Apic timer driver and it has nothing to do
with Xen. So rename it to LocalApicTimerDxe.
After renaming, LocalApicTimerDxe is used in OvmfPkg if CSM_ENABLE=FALSE.
Otherwise 8254 timer is used.
Since LocalApicTimerDxe doesn't depend on OvmfPkg, so it is moved to
UefiCpuPkg.
Patch #1:
Rename XenTimerDxe to LocalApicTimerDxe
Patch #2:
Switch timer in build time for OvmfPkg. If CSM_ENABLE=TRUE, 8254 timer
is used, otherwise the timer is LocalApicTimerDxe.
Patch #3:
Move LocalApicTimerDxe from OvmfPkg to UefiCpuPkg.
Code at: https://github.com/mxu9/edk2/tree/ovmf_lapic_timer.v3
v3 changes:
- Move LocalApicTimerDxe to UefiCpuPkg
- Fix the errors in v2 patch-1 that OvmfXen.dsc / .fdf and
MicrovmX64.dsc / .fdf are not updated for new name.
- Add XenTimerDxe reviewers.
v2 changes:
- Add gEfiMdePkgTokenSpaceGuid.PcdFSBClock in *.dsc
