Update Notes

1. Update code to use CPU_FEATURE_THREE_STRIKE_COUNTER instead of CPU_FEATURE_THREE_STRICK_COUNTER from RegisterCpuFeaturesLib.h as BZ1642 fixed the typo.

2. Removed IntelFrameworkPkg and IntelFrameworkModulePkg. If platforms still use the components in those packages please use the below substitutions:

IntelFrameworkModulePkg/Library/BaseUefiTianoCustomDecompressLib/BaseUefiTianoCustomDecompressLib.inf
==>
MdePkg/Library/BaseUefiDecompressLib/BaseUefiTianoCustomDecompressLib.inf

IntelFrameworkModulePkg/Library/LzmaCustomDecompressLib/LzmaCustomDecompressLib.inf
==>
MdeModulePkg/Library/LzmaCustomDecompressLib/LzmaCustomDecompressLib.inf

IntelFrameworkModulePkg/Library/PeiDxeDebugLibReportStatusCode/PeiDxeDebugLibReportStatusCode.inf
==>
MdeModulePkg/Library/PeiDxeDebugLibReportStatusCode/PeiDxeDebugLibReportStatusCode.inf

IntelFrameworkModulePkg/Library/GenericBdsLib/GenericBdsLib.inf
==>
Switch to the MdeModulePkg BDS MdeModulePkg/Universal/BdsDxe/BdsDxe.inf and drop the above library

3. Removed several legacy framework modules in PcAtChipsetPkg. Platforms can use the below substitutions:

PcAtChipsetPkg/8259InterruptControllerDxe/8259.inf
PcAtChipsetPkg/8254TimerDxe/8254Timer.inf
==>
PcAtChipsetPkg/HpetTimerDxe/HpetTimerDxe.inf
(Please note that platform/silicon codes may still need to mask 8259 interrupts to avoid unexpected interrupts being triggered.)

PcAtChipsetPkg/IsaAcpiDxe/IsaAcpi.inf
==>
Platform specific Super IO bus driver
(An example for OVMF platform can be referred at OvmfPkg/SioBusDxe/SioBusDxe.inf)
