The idle-states binding documentation[1] mentions that the
'entry-method' property is required on 64-bit platforms and must be
set to "psci".

commit a13f18f5 ("Documentation: arm: Fix typo in the idle-states
bindings examples") attempted to fix this earlier but clearly more is
needed.

Fix the cpu-capacity.txt documentation that uses the incorrect value so
we don't get copy-paste errors like these. Clarify the language in
idle-states.txt by removing the reference to the psci bindings that
might be causing this confusion.

Finally, fix devicetrees of various boards to reflect current
documentation.

This introduces dedicated bindings for the system control blocks found
on the A13, A20, A23 and H3 sunxi platforms.

Since the controllers on the A33 are the very same as those on the A23,
no specific compatible is introduced for it.

These bindings are introduced to allow reflecting the differences that
exist between these controllers, that may become significant to driver
implementations.

Following-up on the introduction of a new binding for the A64, this
introduces a system-control binding for the A10 as a replacement of
the sram-controller binding.

This change is motivated by consistency with the Allwinner literature,
that mentions system control over SRAM controller. Moreover, the system
control block is sometimes used for more than SRAM (e.g. for muxing
related to the ethernet PHY).

The poll() changes were not well thought out, and completely
unexplained.  They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.

Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead.  That gets rid of one of the new indirections.

But that doesn't fix the new complexity that is completely unwarranted
for the regular case.  The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.
