clk: imx: Fix an out-of-bounds access in dispmix_csr_clk_dev_data 
When num_parents is 4, __clk_register() occurs an out-of-bounds
when accessing parent_names member. Use ARRAY_SIZE() instead of
hardcode number here.

 BUG: KASAN: global-out-of-bounds in __clk_register+0x1844/0x20d8
 Read of size 8 at addr ffff800086988e78 by task kworker/u24:3/59
  Hardware name: NXP i.MX95 19X19 board (DT)
  Workqueue: events_unbound deferred_probe_work_func
  Call trace:
    dump_backtrace+0x94/0xec
    show_stack+0x18/0x24
    dump_stack_lvl+0x8c/0xcc
    print_report+0x398/0x5fc
