drm: Remove entry points for legacy ioctls
DRM drivers with user-space mode setting have been removed in Linux v6.3. [1] Now remove the ioctl entry points for these drivers. Invoking any of the ioctl ops will unconditionally return -EINVAL to user space. This has already been the behavior for kernels without CONFIG_DRM_LEGACY set.
