Define a new structure type to be used for describing the OF match data. Rather than using the array of spacemit_ccu_clk structures for match data, we use this structure instead. Move the definition of the spacemit_ccu_clk structure closer to the top of the source file, and add the new structure definition below it. Shorten the name of spacemit_ccu_register() to be k1_ccu_register().
