Per the documentation in drm_get_pci_dev(), this function is deprecated
and shouldn't be used anymore. As it turns out, we're going to need to
stop using drm_get_pci_dev() anyway in order to allow us to turn off the
card before full system shutdowns, otherwise we'll hit race conditions
with userspace while trying to tear down the card on shutdown.

So, start using drm_dev_get() and drm_dev_put(), and just turn our
load/unload callbacks into open coded init/fini() functions.

There's literally no difference between any of the backlight init
functions besides the backlight properties they set and the backlight
callbacks that they set, so move all of the duplicated backlight init
code out of there and into nouveau_backlight_init().

This gets rid of a lot of copy pasta!

Changes since v1:
- Some of the pre-refactor callbacks were storing nv_encoder in callback
  data for the backlight devices that they registered, as opposed to
  nouveau_drm. This got missed and caused some bugs that didn't
  originally appear on my setup (NULL kernel derefs) for some reason.
  So, fix this by finding the nouveau_encoder in
  nouveau_backlight_init(), and using that as the callback data for all
  gens instead even if they don't care about the encoder.

Currently module unloading is broken in nouveau due to a rather annoying

While I haven't actually gone into the details of what's causing this to
happen (maybe the kernel removes the backlight device in the device core
before we get to it?), it doesn't really matter anyway because the way
nouveau handles backlights has long since been deprecated.

According to the documentation on the drm_connector->late_register()
hook, the ->late_register() hook should be used for adding extra
connector-related devices. Vice versa, the ->early_unregister() hook is
meant to be used for removing those devices.

So: gut nouveau_drm->bl_list and nouveau_drm->backlight, and replace
them with per-connector backlight structures. Additionally, move
backlight registration/teardown into the ->late_register() and
->early_unregister() hooks so that DRM can give us a chance to remove
the backlight before the connector is even removed. This appears to fix
the problem once and for all.

Changes since v2:
- Use NV_INFO_ONCE for printing GMUX information, since otherwise this
  will end up printing that message for as many times as we have
  connectors

Currently we return NOTIFY_DONE for any event which we don't think is
ours. However, many laptops will send more then just an ATIF event and
will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't
check for this, we return NOTIFY_DONE which causes a keypress for the
ACPI event to be propogated to userspace. This is the equivalent of
someone pressing the display key on a laptop every time there's a
hotplug event.

So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses
from them.
