This has a couple of advantages:
* Completely hides struct clk from many clock platform drivers and static
clock initialization code.
* Simplifies the generic clk_register() function and allows adding optional
fields in the future without modifying the function signature.
* Allows for simpler static initialization of clocks on all platforms by
removing the need for forward delcarations.
* Halves the number of symbols added for each static clock initialization.
