Ivan Lipski c61eda4343 drm/amd/display: Check for S0i3 to be done before DCCG init on DCN21

[WHY]
On DCN21, dccg2_init() is called in dcn10_init_hw() before
bios_golden_init(). During S0i3 resume, BIOS sets MICROSECOND_TIME_BASE_DIV
to 0x00120464 as a marker. dccg2_init() overwrites this to 0x00120264,
causing dcn21_s0i3_golden_init_wa() to misdetect the state and skip golden
init.
Eventually during the resume sequence, a flip timeout occurs.

[HOW]
Skip DCCG on dccg2_is_s0i3_golden_init_wa_done() on DCN21.
