NXP devices with QBMan version 5 and above can enable software
portals that are memory backed. This allows the portal to be
mapped as cacheable/sharable (same as all normal memory) so
that portals can freely migrate between cores and clusters
in the SoC. The driver will enable this mode by default when
appropriate HW support is detected.

The timeout for QBMan Management Commands can falsely trigger on a
busy system. This patch doubles the timeout to avoid the
false error reports

Add FQ (Frame Queue) and BP (Buffer Pool) query APIs that
users of QBMan can invoke to see the status of the queues
and pools that they are using.

Move the NXP DPIO (Datapath I/O Driver) out of the
drivers/staging directory and into the drivers/soc/fsl directory.
The DPIO driver enables access to Queue and Buffer Manager (QBMAN)
hardware on NXP DPAA2 devices. This is a prerequisite to moving the
DPAA2 Ethernet driver out of staging.
