Subject: [PATCH 07/11] clk: sunxi: add generic allwinner,sunxi name

The only difference between the different compatible matches at the
end of clk-sunxi.c are the critical clocks. Two SoCs get away so far
without any, so there is no reason to enumerate those SoCs in here
explicitly, though we have to keep them in for compatibility reasons.

Rename the init function to highlight this generic feature and add a
new, generic DT compatible string which can be used as a fallback value
in the future should a particular SoC don't need any special treatment.
