Once we enable the cacheable portal memory, we need to do
cache flush for enqueue, vdq, buffer release, and management
commands, as well as invalidate and prefetch for the valid bit
of management command response and next index of dqrr.

NXP arm64 based SoC needs to allocate cacheable and
non-shareable memory for the software portals of
Queue manager, so we extend the arm64 ioremap support
for this memory attribute.

allocate stash transcations of QBMan should be
issued as cachable and non-coherent(non-sharable), we
need to configure this region to be non-shareable.

with cache-enable
and non-shareable first, then enables the CENA portal memory
access in the QBMan driver, at last changes the ioremap call
in dpio driver where the software portal CENA memory is
mapped to be the correct one.
