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.

Without proper regulator support for individual boards, it is dangerous
to have overclocked/overvoltaged OPPs in the list. Cpufreq will increase
the frequency without the accompanying voltage increase, resulting in
an unstable system.

Remove them for now. We can revisit them with the new version of OPP
bindings, which support boost settings and frequency ranges, among
other things.
