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.
