dpaa: Migrate from NCSW base to a home-grown driver

The NCSW reference base requires tuning for each target, and currently
is configured for FMANv2.  This doesn't readily work on FMANv3 devices,
such as the T-series powerpc, or the LS1043 ARM.  Since Freescale/NXP
abandoned the NCSW driver a decade ago, it makes sense to abandon it
ourselves as well.  This new driver uses a combination of the NCSW
driver and the Linux driver (BSD/GPL dual licensed) as a reference, but
contains no actual code from them.

The DPAA (Data Path Acceleration Architecture) subsystem consists of the
following components:

* BMan -- Buffer Manager.  Manages buffer pools of different sizes (one
  size per pool, up to 64 pools)
* QMan -- Queue Manager.  Manages the interfaces between DPAA-based
  components and the CPU(s).
* FMan -- Frame Manager.  Responsible for all ethernet-related
  processing.  Consists itself of the following components:
  * Ports -- interfaces to the QMan.  An ethernet interface consists of
    2 ports.
    Ports use "Next-invoked action" (NIA) descriptors to form a pipeline
    for processing on receive and transmit.
  * Parser -- performs protocol header parsing and validation.  Both
    hardware and software parsers are available.
  * KeyGen -- Key generator, used to start the classification process
    (for the Policer), generating FQIDs and other keys based on the
    frame input.
  * Policer -- performs traffic shaping and classification
* MAC -- SoC specific ethernet MAC (dTSEC, TGEC, mEMAC).  Currently
  supports dTSEC and mEMAC, along with their MDIO blocks.

Additional components not yet handled:
SEC -- Security engine (crypto)
RE -- RAID engine
RapidIO
DCE -- Decompression/Compression engine, supports ZLIB, DEFLATE, and
GZIP, as well as base64 encoding and decoding.

BMan and QMan are accessed via cache-coherent portals, using ring
buffers as I/O.  The intent is for portals to be per-CPU (core/thread)
to reduce locking contention and improve performance.  This driver pins
interrupt handlers to the CPU "owning" a given portal, and uses critical
sections to prevent switching while accessing the portal.
