The A10s and A13 have a few SRAM that can be mapped either to a device or
to the CPU, with the mapping being controlled by a SRAM controller.

Add the SRAM controller, the SRAM that it drives and the section that can
be used by the various devices.

The A13 and the A10s use the same die (this has been confirmed by Allwinner),
as such there is no need to differentiate between the ehci/ohci parts of both,
the only reasons there were different allwinner,sun5i-a*-foo compatible
between these 2 parts is costemetically and because we could when we still
had 2 completely different dtsi files.

The allwinner,sun5i-a*-foo compatible strings are not used for binding at all,
the actual driver binds to the generic-?hci compatible, so we can safely remove
this cosmetical difference and simplify the dtsi files.

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.

In order to make it easier for them to reuse our device trees, relicense our
DTSI first under a GPL/X11 dual-license. Hopefully, the DTS will follow soon.

Review of the u-boot sunxi simplefb patches has led to the decision that
u-boot should not use a specific path to find the nodes as this goes contrary
to how devicetree usually works.

Instead a platform specific compatible + properties should be used for this.

The simplefb bindings have already been updated to reflect this, this patch
brings the sunxi devicetree files in line with the new binding, and the
actual u-boot implementation as it is going upstream.

Note for now we point directly to the parent rather then to the de_be0 mod-clk
