[PATCH 1/1] drm/amdgpu: Use amdgpu by default on SI dedicated GPUs

["Timur Kristóf" <timur.kristof@gmail.com>]

Now that the DC analog connector support and VCE1 support landed,
SI dGPUs are at feature parity with the old radeon driver.

Enabling the amdgpu driver by default for SI dGPUs has the
following benefits:

- More stable OpenGL support through RadeonSI
- Vulkan support through RADV
- Improved performance
- Better display features through DC

Users who want to keep using the old driver can do so using:
amdgpu.si_support=0 radeon.si_support=1
