dc->clk_mgr is checked for NULL earlier in dcn50_init_hw() and
dcn60_init_hw(), but dcn50_initialize_min_clocks() and
dcn401_initialize_min_clocks() are called without any guard,
causing Smatch to report potential NULL dereferences.
Guard both call sites with the same pattern used throughout
both functions:
if (dc->clk_mgr && dc->clk_mgr->funcs)
Also fix dcn50_initialize_min_clocks() which calls
get_dispclk_from_dentist without checking the function pointer,
unlike the dcn401 equivalent which guards that call.
Fix kernel-doc in dcn60_hwseq.c by adding missing parameter descriptions
for @probe in dcn60_update_probe_status() and @type in
is_probe_measurement_type_for_hubbub().
