'valid' field in MemoryRegionOps struct indicates how the MemoryRegion
can be accessed by the guest. In the previous code, the 'valid' field
was not specified explicitly. As a result, the CMB area could only be
accessed in units of 4 bytes.
This commit specifies the 'valid' field in MemoryRegionOps of CMB and
the CMB area can be accessed in units of 8 bytes.
