v3d: noop drm-shim raises some warnings
Things still work, but when using the drm noop shim driver we get an output like that:
Unknown DRM_IOCTL_V3D_GET_PARAM 8
Unknown DRM_IOCTL_V3D_GET_PARAM 9
Unknown DRM_IOCTL_V3D_GET_PARAM 10

Thread 0 took 0.17 seconds and compiled 2 shaders (not including SIMD16) with 1 GL context switches
That includes those Unknown warning. @eric confirmed that happens on the CI too: #5932 (comment 2096187)
And quoting @itoral:
I would guess those warnings are for new parameters we query from the kernel at screen init time that need to be explicitly supported in drm-shim. If it is that, it should not be very important but it should also be fairly trivial to fix.
