2.7.4
The suniv (new F-series) chip has a timer with less functionality than
the A10 timer, e.g. it has only 3 channels.
Add a new compatible for it. As we didn't use the extra channels on A10
either now, the code needn't to be changed.
The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer.
Register sun4i_timer as sched_clock on it.

F1C100s is one product with the suniv die, which has a 32MiB co-packaged
DDR1 DRAM chip. As we have the support for suniv pin controller and CCU now, add a
initial DTSI for it.

This isn't the proper SPDX format, and this is reported by
checkpatch. I've fixed it while applying, but please make sure to run
checkpatch.

Thanks Maxime, I will be more carefull next time. I actually saw that
warning, but I couldn't find what to do. I have looked to [1] and saw that
its spelled correctly. Now I think problem is, the licencse identifier
should be separate comment like:
// SPDX-...
Thanks!
