The function name not_share_unassigned_cvt() is opposite to what it does.
This patch renames it to intel_not_share_assigned_cvt(), and addes comments
to explain why some Intel display codecs need this workaround.

NVIDIA HDMI codecs do not seem to follow the Audio Sample Packet (ASP)
channel mapping (as set by verb F32h per HDA specification 7.3.3.41)
when playing back 2-channel audio (CEA CA 0x00).

Basically this means that specifying swapped channels for stereo audio
(FR,FL) does not take effect, and e.g. this command plays back on the
wrong channel:
speaker-test -c2 -Dhdmi:CARD=NVidia,DEV=0 -m FR,FL -s1

Multichannel audio is not affected.

This issue has been confirmed to exist on codec 0x10de0015 by me and on
0x10de0040 by Juho Teperi.

Disable 2ch FL/FR channel swapping on all NVIDIA HDMI codecs that use
the standard HDA channel mapping system. Since this is a very minor
functionality loss, we err on the side of disabling it for newer codecs
as well until any future testing confirms that this issue has been
fixed.

For Valleyview display codec, if an unused pin chooses an assgined converter
selected by a used pin, playback on the unused pin can also give sound to the
output device of the used pin. It's because data flows from the same convertor
to the display port of the used pin. This issue is same as Haswell.

So this patch avoids using assinged convertors for unused pins.
The related function haswell_config_cvts() is renamed for code reuse.

This is provoked when the ASoC front end is open along with its backend,
(which causes the backend to have a runtime assigned to it) and then the
SNDRV_CTL_IOCTL_PCM_INFO is requested for the (visible) backend device.

Resolve this by ensuring that ASoC internal backend devices are not
visible to userspace, just as the commentry for snd_pcm_new_internal()
says it should be.
