Subject: [PATCH 03/18] clk: meson: migrate a1 clock drivers 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
in order to finally get rid on the NR_CLKS define.
