Arm documentation does not explicitly report the order of the two
32bit words that compose the 64bit value. But both ADIv5 and ADIv6
specify that only little-endian is supported (ADIv5.2 obsoletes
the big-endian support). This change reads the 64bit value in
little-endian.
Detect the 64bit content and use it.
