drm/amdgpu: remove set but not used variable 'dig_connector'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/amdgpu/atombios_dp.c: In function
‘amdgpu_atombios_dp_get_panel_mode’:
drivers/gpu/drm/amd/amdgpu/atombios_dp.c:364:36: warning: variable
‘dig_connector’ set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.

Fixes: d38ceaf99ed0 ("drm/amdgpu: add core driver (v4)")
