19d3b47b92 sys/mips: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

d6141d33bc Add initial support for the QCA953x ("Honeybee") from Qualcomm Atheros.
The QCA953x SoC is an integrated 2x2 2GHz 11n + MIPS24k core, with
a 5 port FE switch, gige WAN port, and all the same stuff you'd find on
its predecessor - the AR9331.

However, buried deep in here somewhere is also a PCIe EP/RC for various
applications and some other weird bits I don't yet know about.

This is enough to get the reference board up and booting.  I haven't yet
had it pass lots of packets - I need to finalise the ethernet switch
bits and the GMAC configuration (ie, how the ethernet ports and switch
are wired up) and I'll bring that in when I commit the base configuration
files to use the thing.

The wifi stuff will come much later.  I have to port that support from
Linux ath9k and extend our vendor HAL to support it.

The reference board (AP143) comes with 32MB RAM and 4MB flash, so in order
to use it I need to get USB working fully so I can run root from there.

Thankyou to Qualcomm Atheros for access to the reference design board.

Details:

* Add register definitions from openwrt;
* It looks like a QCA955x but shrunk down to a QCA933x footprint, so
  use the QCA955x bits and fix up the clock detection code to do the
  QCA953x bits (they're very subtly different);
* Teach GPIO about it;
* Teach EHCI about it;
* Teach if_arge about it;
* Teach the CPU detection code about it.

Tested:

* AP143, QCA9533v2 SoC

70bd9230d1 Preparation work for supporting the AR91xx and AR724x.
* Implement a SoC probe function, from Linux, which determines the
  SoC family, type and revision. This only probes the AR71xx series
  SoC and (currently) panics on others.

* Migrate some of the AR71XX specific hardware init (USB device, determining
  system frequencies) into using the cpuops introduced in an earlier commit.
  Other SoC specific hardware stuff (per-device flush/WB, GPIO pin wiring,
  Ethernet PLL setup, other things I've likely missed) will be introduced in
  subsequent commits.
