The hardware descriptors have big endian (BE) format.
Provide proper endianness handling for the remaining
descriptor fields, to ensure they are correctly
accessed by non-BE CPUs too.

There are multiple occurences of both contextB and context_b
in different h/w descriptors, referring to the same descriptor
field known as "Context B". Stick with the "context_b" naming,
for obvious reasons including consistency (see also context_a).

Preventively mask every access to the 'fqid' h/w field,
since it is defined as a 24-bit field, for every h/w
descriptor.  Add generic accessors for this field to
ensure correct access.

This driver enables the Freescale DPAA 1.x Queue Manager block.
QMan is a hardware accelerator that manages frame queues.  It allows
CPUs and other accelerators connected to the SoC datapath to enqueue
and dequeue ethernet frames, thus providing the infrastructure for
data exchange among CPUs and datapath accelerators.
