Add clk_regmap_init() and use it with all clock types which derive from
clk_regmap. This helps initialise clk_regmap clocks without requiring
tables to keep track of the clock using this type.
The way it is done couples clk_regmap with the controllers, which is not
ideal. This is a temporary solution to get rid of the tables. The situation
will eventually be improved.

Symbols exported by the Amlogic clock modules are only meant to be used by
Amlogic clock controller drivers. Using a dedicated symbols namespace make
that clear and help clean the global namespace of symbols other modules do
no need.

clk_ops.round_rate will be removed at some point. It's replacement is
.determine_rate. Switch clk-cpu-dyndiv over to use .determine_rate.

Add a clock driver for the cpu dynamic divider, this divider needs
to have a flag set before setting the divider value then removed
while writing the new value to the register.
This drivers implements this behavior and will be used essentially
on the Amlogic G12A and G12B SoCs for cpu clock trees.
