[PATCH] clk: Annotate struct clk_hw_onecell_data with __counted_by

[Stephen Boyd <sboyd@kernel.org>]

Quoting Kees Cook (2023-08-17 13:30:22)
> Prepare for the coming implementation by GCC and Clang of the __counted_by
> attribute. Flexible array members annotated with __counted_by can have
> their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
> (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
> functions).
> 
> As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data.
> Additionally, since the element count member must be set before accessing
> the annotated flexible array member, move its initialization earlier.
