46309b1101 UefiCpuPkg/MtrrLib: Add PCD PcdCpuNumberOfReservedVariableMtrrs 
Current MtrrLib reserves 2 variable MTRRs for some legacy OS boot (CSM boots)
may require some MTRRs to be reserved for OS use. But UEFI OS boot will not use
MTRRs.

Per Scott's suggestion in
link: http://article.gmane.org/gmane.comp.bios.edk2.devel/4099
Add one PCD PcdCpuNumberOfReservedVariableMtrrs to specify the number of
variable MTRRs reserved for OS use. Setting its default value to 2 is for
back-compatibility.

0a4f7aa056 UefiCpuPkg/MtrrLib: MtrrValidBitsMask and MtrrValidAddressMask wrong 
Per IA32 SDM, if CPUID.80000008H is not available, software may assume that the
processor supports a 36-bit physical address size.
However, for such old processors (For example, Quark processor),
MtrrValidBitsMask and MtrrValidAddressMask values are reverted and wrong in
MtrrLib. MtrrValidBitsMask should be 0xFFFFFFFFFULL and MtrrValidAddressMask
should be 0xFFFFFF000ULL.

44c8400a7d MtrrDebugPrintAllMtrrs() should loop until the max physical address is reached. 
GetMemoryCacheTypeFromMtrrType () should return the default memory type instead of UC type for MTRR_CACHE_INVALID_TYPE.
