If we are in RAS triggered situation and
BACO isn't support, emergency restart is needed,
and this code is only needed for some specific
cases(vega20 with given smu fw version).

After we add smu mode1 reset for sienna cichlid, we
need to share AMD_RESET_METHOD_MODE1 with psp mode1 reset,
so in amdgpu_device_gpu_recover, we need differentiate
which mode1 reset we are using, then decide if it's
a full reset and then decide if emergency restart is needed,
the logic will become much more complex.

After discussion with Hawking, move emergency restart logic

b448d30b0c drm/amd/display: OLED panel backlight adjust not work with external display connected 
[Why]
amdgpu_dm->backlight_caps is for single eDP only. the caps are upddated
for very connector. Real eDP caps will be overwritten by other external
display. For OLED panel, caps->aux_support is set to 1 for OLED pnael.
after external connected, caps+.aux_support is set to 0. This causes
OLED backlight adjustment not work.

[How]
within update_conector_ext_caps, backlight caps will be updated only for
eDP connector.
