This allows multiple instances of SoCs that use the pl310 driver to be
built within the same kernel:
* Add access to the platform_t object from outside platform.c
* Use this with the pl310 driver
There is a new platform_pl310 interface to replace the existing code. SoCs
need to implement the init method, and if they have special requirements to
write to the two registers we care about will also need to implement the
write_ctrl and write_debug methods.

H2+ SoC is a stripped down version of H3 without gigabit ethernet and 4K HDMI.
Also add sun8i-h2-plus-orangepi-zero.dts to the build as we run on this board.
cfumass(4) is not usable if usfs(4) is loaded or compiled into the
kernel. Remove usfs so that the user may kldload the USB mass storage
target they prefer.

- 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.

While here:
- remove 'device mii' - included by miibus;
- remove 'device smcphy' - included by miibus;
- sorted the network drivers list;
- added a comment about miibus based on amd64/GENERIC.

Push-Pull Two Wire interface is a almost compatible iic like bus used
in sun6i SoC. It's only use is to communicate with the power management IC.

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.

SMP SoCs and qemu virt. Further SoCs can be supported if they support the
PLATFORM, PLATFORM_SMP, and MULTIDELAY options.
