drm: Allow const struct drm_driver
It's nice if a big function/ioctl table like this is const. Only
downside here is that we need a few more #ifdef to paper over the
differences when CONFIG_DRM_LEGACY is enabled. Maybe provides more
motivation to sunset that horror show :-)
v2:
- Fix super important checkpatch warning (Sam)
- Update the kerneldoc example too (Sam)
