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.

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.

60245f5103 Fix the handling of pull-up and pull-down for RK3188.
For this to work the driver needs to know the bank it has attached to since

1c15a29600 Reduce the maximum number of pins for the Rockchip RK3188, this driver
isn't supposed to manage all the GPIO pins in the system from a single
instance, instead it will attach to each one of the four available GPIO
controllers and only deal with one bank at time (32 pins per bank).

Rework part of the driver to take advantage of that, this simplify the
code a lot.

Also fix a bug in rk30_gpio_get_function() which wouldn't return the
correct values.

While here fix a typo in register name.
