History
Adrian Chadd c37904e8ba Reshuffle all of the DDR flush operations into a single switch/mux, 
and start teaching subsystems about it.

The Atheros MIPS platforms don't guarantee any kind of FIFO consistency
with interrupts in hardware.  So software needs to do a flush when it
receives an interrupt and before it calls the interrupt handler.

There are new ones for the QCA934x and QCA955x, so do a few things:

* Get rid of the individual ones (for ethernet and IP2);
* Create a mux and enum listing all the variations on DDR flushes;
* replace the uses of IP2 with the relevant one (which will typically
  be "PCI" here);
* call the USB DDR flush before calling the real USB interrupt handlers;
* call the ethernet one upon receiving an interrupt that's for us,
  rather than never calling it during operation.

Tested:

* QCA9558 (TP-Link archer c7 v2)
* AR9331 (Carambola 2)

TODO:

* PCI, USB, ethernet, etc need to do a double-check to see if the
  interrupt was truely for them before doing the DDR.  For now I
  prefer "correct" over "fast".
