[ Upstream commit 96ce96f8773da4814622fd97e5226915a2c30706 ]
amdgpu_device_asic_has_dc_support() just checks the asic itself.
amdgpu_device_has_dc_support() is a runtime check which not
only checks the asic, but also other things in the driver
like whether virtual display is enabled. We want the latter
here.
