drm/amdgpu: Use amdgpu by default on SI dedicated GPUs (v2)

Browse Source 
Now that the DC analog connector support and VCE1 support landed,
amdgpu is at feature parity with the old radeon driver
on SI dGPUs.

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

v2:
- Update documentation in Kconfig file

Choose this option if you want to enable experimental support
Choose this option if you want to enable support
for SI (Southern Islands) asics.
SI is already supported in radeon. Experimental support for SI
in amdgpu will be disabled by default and is still provided by
radeon. Use module options to override this:
SI (Southern Islands) are first generation GCN GPUs,
supported by both drivers: radeon (old) and amdgpu (new).
By default, SI dedicated GPUs are supported by amdgpu.

To use radeon for SI,
