93a065e749 Remake support for SMP kernel on UP cpu:
- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
   By this, any SMP kernel can be compiled with SMP_ON_UP support.
 - Enable runtime detection of CPU multiprocessor extensions only
   if SMP_ON_UP option is used. In other cases (pure SMP or UP),
   statically compile only required variant.
 - Don't leak multiprocessor instructions to UP kernel.
 - Correctly handle data cache write back to point of unification.
   DCCMVAU is supported on all armv7 cpus.
 - For SMP_ON_UP kernels, detect proper TTB flags on runtime.

1834282de6 Split CPU_CORTEXA into CPU_CORTEXA8, for the Cortex-A8, and CPU_CORTEXA_MP,
for later Cortex-A CPUs that support the Multiprocessor Extensions. This
will be needed to support both in a single GENERIC kernel while still
being able to only build for a single SoC.

2b3ad18853 [intrng] Migrate the intrng code from sys/arm/arm to sys/kern/subr_intr.c.
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.

7ce00ee7b4 Rename arm_init_secondary_ic() -> arm_pic_init_secondary(). The latter is
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.

5df539274f Add alternate descriptors support for if_dwc.
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).
