cb17fff3a254 ("drm/amdgpu/mes: remove unused functions")
removed most of the code using these IDRs but forgot to remove the struct
members and init/destroy paths.

There is also interrupt handling code in SDMA 5.0 and 5.2 which appears to
be using it, but is is unreachable since nothing ever allocates the
relevant IDR. We replace those with one time warnings just to avoid any
functional difference, but it is also possible they should be removed.

v2: also fix up gfx_v12_1.c and sdma_v7_1.c
