Since Linux 4.9-4.10 DTS doesn't have clocks under /clocks but only a ccu node.
Currently only H3 is supported with almost the same state as HEAD.
(video pll aren't supported for now but we don't support video).
This driver and clocks will also be used for other SoC (A64, A31, H5, H2 etc ...)

- 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.

Add basic support for A33/R16 that is enough to boot a kernel.
This adds the platform code, padconf data and the new clocks strings.

The audio controller in the H3 is more or less the same as A10/A20 except
some registers are shuffled around. The mixer interface, however, is
completely different between SoCs. Separate a10_mixer_class and
h3_mixer_class implementations are now made available. This will also make
adding support for other SoCs easier in the future.
