clk: en7523: Initialize num before accessing hws in en7523_register_clocks()
[ Upstream commit 52fd1709e41d3a85b48bcfe2404a024ebaf30c3b ]
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: f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with __counted_by")
