clk: Annotate struct clk_hw_onecell_data with __counted_by
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.
