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_eeclkc_data struct to finally get rid on the
NR_CLKS define.
