intr_pic_init_secondary. Replace them with a direct call. On BCM2836
and ARMADA XP we need to add this function, but it can be empty.

slightly wrong on the others. We should just check if mp_ncpus is set to
more than one CPU as we may wish to run on a single core even when SMP is
available.

Only L2 PIPT cache is supported for __ARM_ARCH >= 6.
In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.
The ci20 port (by kan@) is going to reuse almost all of the intrng code
since the SoC in question looks suspiciously like someone took an ARM
SoC design and replaced the ARM core with a MIPS core.
* migrate out the code;
* rename ARM_ -> INTR_;
* rename arm_ -> intr_;
* move the interrupt flush routine from intr.c / intrng.c into
arm/machdep_intr.c - removing the code duplication and removing
the ARM specific bits from here.
Thanks to the Star Wars: The Force Awakens premiere line for allowing
me a couple hours of quiet time to finish the universe builds.
Tested:
* make universe
TODO:
* The structure definitions in subr_intr.c still includes machine/intr.h
which requires one duplicates all of the intrng definitions in
the platform code (which kan has done, and I think we don't have to.)
Instead I should break out the generic things (function declarations,
common intr structures, etc) into a separate header.
* Kan has requested I make the PIC based IPI stuff optional.
the name the function will have when the new ARM_INTRNG code is integrated,
and doing this rename first will make it easier to toggle the new interrupt
handling code on/off with a config option for debugging.
This also adds a newbus interface that allows a SoC to override the
following settings:
- if_dwc specific SoC initialization;
- if_dwc descriptor type;
- if_dwc MII clock.
This seems to be an old version of the hardware descriptors but it is
still in use in a few SoCs (namely Allwinner A20 and Amlogic at least).
Tested on Cubieboard2 and Banana pi.
Tested for regressions on Altera Cyclone by br@ (old version).
