Sean Anderson f9c7d4f99f clk: Add K210 clock support
Due to the large number of clocks, I decided to use the CCF. The overall
structure is modeled after the imx code. Clocks parameters are stored in
several arrays, and are then instantiated at run-time. There are some
translation macros (FOOIFY()) which allow for more dense packing.
