The support is done in backwards compatible extension, in which the new u32 clock identifier fields are only used if the existing u8 size clock identifier is set as 255. In all the other cases, the existing u8 clock identifier is used. As the size of the messages sent / received is not verified for existing devices / old firmware, increasing the size of the messages from the end is also fine. Due to this reason, depending on ABI version isn't necessary either.

Add macros that can take either one single struct clk_hw *, or an array of them, for drivers to use. A special CLK_HW_INIT_HWS macro is included, which takes an array of struct clk_hw *, but sets .num_parents to 1. This variant is to allow the reuse of the array, instead of having a compound literal allocated for each clk sharing the same parent.
