A second set of device tree changes, this time switching a few SoCs to the
new sunxi-ng clock framework. We also added the support for a new SoC

To maintain bisectability, while avoiding some un-trivial merge

We create a procfs directory for every PCI bus. Previously, the directory
name was just the bus number, so using the same bus number in different
domains caused a kernel crash when we tried to create a duplicate
directory.
Make pci_proc_domain() return the domain number, so procfs directories for
buses in domain 0 are named with just the bus number, and directories for
buses in other domains include both the domain number and the bus number.

Commit f70ddc07b6 ("MIPS: c-r4k: Avoid small flush_icache_range SMP
calls") adds checks to force use of hit-type cache ops for small icache
flushes where they are globalised & index-type cache ops aren't, in
order to avoid the overhead of IPIs in those cases. However it
calculated the size of the region being flushed incorrectly, subtracting
the end address from the start address rather than the reverse. This
would have led to an overflow with size wrapping round to some large
value, and likely to the special case for avoiding IPIs not actually
being hit.

As noted in commit 3ebee5a2e1 ("arm64: dts: kill skeleton.dtsi"),
there are a number of problems with skeleton.dtsi, and it would be
prefereable to remove it entirely. As there are a large number of
existing users, fixing these up will take a while.
This patch adds a note to arm's skeleton.dtsi noting that this is the
case, to make this more obvious and hopefully minimize new uptake of
skeleton.dtsi in the mean time.
