Nesting container_of() causes warnings with W=2, which is
annoying if it happens in headers and fills the build log
like:

Redefine two copies of the to_clk_regmap() macro as inline functions
to avoid a lot of these.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

Add a clock type that associates a regmap pointer and some
enable/disable bits with a clk_hw struct. This will be the struct
that a hw specific implementation wraps if it wants to use the
regmap helper functions.
