eb10a26460 clk: meson: aoclk: move bindings include to main driver 
Now the clock ids are no more defined in private headers,
cleanup and include the dt-bindings headers from the main
driver file.

7e1723fd3f clk: meson: migrate meson-aoclk out of hw_onecell_data to drop NR_CLKS 
The way hw_onecell_data is declared:
  struct clk_hw_onecell_data {
          unsigned int num;
          struct clk_hw *hws[];
  };

makes it impossible to have the clk_hw table declared outside while
using ARRAY_SIZE() to determine ".num" due to ".hws" being a flexible
array member.

Completely move out of hw_onecell_data and add a custom
devm_of_clk_add_hw_provider() "get" callback to retrieve the clk_hw
from the meson_aoclk_data struct to finally get rid on the
NR_CLKS define.

20425f6319 clk: meson: enable building as modules 
Make it possible to build all clk drivers as modules, but default
remains built-in.

No functional changes.

ba62608110 clk: meson: g12a-aoclk: migrate to the new parent description method 
This clock controller use the string comparison method to describe parent
relation between the clocks, which is not optimized.

Migrate to the new way by using .parent_hws where possible (when parent
clocks are localy declared in the controller) and use .parent_data
otherwise.

Remove clk input helper and all bypass clocks (declared in probe function)
which are no longer used since we are able to use device-tree clock name
directly.
