The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to
indicate MSR/MMIO address. It's ok for MSR because MSR address is UINT32 type
actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB.

The input parameter Index of PreSmmCpuRegisterTableWrite() and
CpuRegisterTableWrite() is defined as UINT32. Index is MSR/MMIO address that
will be saved in CPU register table. UINT32 blocks the MMIO address > 4GB.
This fix is to define Index to UINT64 instead of UINT32.

The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to
indicate MSR/MMIO address. It's ok for MSR because MSR address is UINT32 type
actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB.
This update on CPU_REGISTER_TABLE_ENTRY is to add additional UINT32 field
HighIndex to indicate the high 32bit MMIO address and original Index still
indicate the low 32bit MMIO address.
This update makes use of original padding space between ValidBitLength and
Value to add HighIndex.
