clk: en7523: Initialize num before accessing hws in en7523_register_clocks()

Browse Source 
With the new __counted_by annotation in clk_hw_onecell_data, the "num"
struct member must be set before accessing the "hws" array. Failing to
do so will trigger a runtime warning when enabling CONFIG_UBSAN_BOUNDS
and CONFIG_FORTIFY_SOURCE.

Fixes: f316cdff8d ("clk: Annotate struct clk_hw_onecell_data with __counted_by")
