[PATCH 0/1] Use amdgpu by default on SI dGPUs

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

Based on my earlier series:
"Use amdgpu by default on CIK dGPUs"

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

Why?

Compared to the old radeon driver, amdgpu offers better
performance, more display features through DC,
as well as support for Vulkan 1.3 through RADV.

What can these GPUs actually do on amdgpu?

Tahiti and Pitcairn can play some modern games, albeit
at lower resolutions and lower frame rates. They are
mainly held back by a low amount of VRAM (2~3 GiB).
The other SI "gaming" GPUs are mainly useful for
playing games from their era (the mid-2010s)
or less demanding games in general.

As a reminder, SI dedicated GPUs are the following:
