[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.

[WHY]
We're checking surface and stream updates after they've been applied to
their respective states within `update_planes_and_stream_state`.
Medium updates under the HWSS V3 fast path that are not supported or
tested are getting implicitly if they don't trigger a DML validation
and getting updated in place on the dc->current_state context.
[HOW]
Fix this issue by moving up the fast path determination check prior
to `update_planes_and_stream_state`. This is how the V2 path works
and how the V3 path used to work prior to the refactors in this area.
