To be consistent with CAAM engine HW spec: in case of 64-bit registers,
irrespective of device endianness, the lower address should be read from
/ written to first, followed by the upper address. Indeed the I/O
accessors in CAAM driver currently don't follow the spec, however this
is a good opportunity to fix the code.
