by starting address StartAddress by using 64-bit access. The total number
of byte to be copied is specified by Length. Length is returned.
If StartAddress is not aligned on a 64-bit boundary, then ASSERT().
If Length is greater than (MAX_ADDRESS - StartAddress + 1), then ASSERT().
If Length is greater than (MAX_ADDRESS -Buffer + 1), then ASSERT().
If Length is not aligned on a 64-bit boundary, then ASSERT().
If Buffer is not aligned on a 64-bit boundary, then ASSERT().
@param StartAddress Starting address for the MMIO region to be copied to.
@param Length Size in bytes of the copy.
@param Buffer Pointer to a system memory buffer containing the data to write.
@return Size in bytes of the copy.
