clk: sun5i: Add compatibles for Allwinner A13
The A13 has a lot less clocks than the one found in the Allwinner A10. Add these stripped down clocks to the clock driver and in the documentation.

Clock consumers should specify the desired clocks they use with a

"clocks" phandle cell. Consumers that are using a gated clock should

provide an additional ID in their clock property. The values of this

ID are documented in sunxi/<soc>-gates.txt.
