drm/amd: Fix renoir/green sardine MP0 IP version detection

The existing codebase never had a case for detecting MP0 version on
Renoir and instead relied upon hardcoded chip name.  This was missed as
part of the changes to migrate all IP blocks to build filenames from
`amdgpu_ucode.c`.

Consequently, Renoir tries to fetch a binary with 11_0_3 in the filename
and since it's supposed to have "renoir" in the filename fails to probe.
The fbdev still works though so the series worked.

Add a case for Renoir into the legacy table to ensure the right ASD and
TA firmware load again.
