drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to use

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!
