This adds a list of valid SRAM sections compatibles for the A13, A20,
A23 and H3 platforms. Per-platform compatibles are introduced for the
SRAM sections of these platforms, with the A10 compatibles also listed
as valid when applicable.
In particular, compatibles for the C1 SRAM section are introduced. Other
SRAMs (C2 and C3 in particular) are left out. They will be added we needed.

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 SRAM mapping controls on Allwinner SoCs is located in a block called
"System Controls". This block also has registers for identifying the SoC,
reading the state of an external boot-related pin, and on some newer SoCs,
glue layer controls for the EMAC Ethernet controller.
The A64 variant compatible is renamed to "allwinner,a64-system-control"
to reflect this. The old A64 compatible is deprecated. So far we haven't
seen any actual use of it.

Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`
Some unnecessary changes were manually fixed.

Introduce a new "protect-exec" reserved sram area type which is
makes use of the the existing functionality provided for the "pool"
sram region type for use with the genalloc framework and with the
added requirement that it be maintained as read-only and executable
while allowing for an arbitrary number of drivers to share the space.
This introduces a common way to maintain a region of sram as read-only
and executable and also introduces a helper function, sram_exec_copy,
which allows for copying data to this protected region while maintaining
locking to avoid conflicts between multiple users of the same space. A
region of memory that is marked with the "protect-exec" flag in the
device tree also has the requirement of providing a page aligned block
of memory so that the page attribute manipulation does not affect
surrounding regions.
Also, selectively enable this only for builds that support set_memory_*
calls, for now just ARM, through the use of Kconfig.

Some SRAM users may require non-bufferable access to the memory, which is
impossible, because devm_ioremap_wc() is used for setting sram->virt_base.

method, using DT property. Documentation is updated accordingly.

SRAM bindings for various SoCs, using the mmio-sram genalloc
API, are spread over different places - per SoC vendor. Since all of
these are quite similar (they depend on mmio-sram) move them to a common
place.
