Commit d455b45f83 ("v4l: vsp1: Add support for new VSP2-BS, VSP2-DL,
and VSP2-D instances") added support for the VSP2-D found in the R-Car
V3M (R8A77970) but the video output that VSP2-D sends to DU has a greenish
garbage-like line repeated every 8 screen rows. It turns out that R-Car
V3M has the LIF0 buffer attribute register that you need to set to a non-
default value in order to get rid of the output artifacts.
Based on the original (and large) patch by Daisuke Matsushita
<daisuke.matsushita.ns@hitachi.com>.

To allow dual pipelines utilising two WPF entities when available, the
VSP was updated to support header-mode display list in continuous
pipelines.
A small bug in the status check of the command register causes the
second pipeline to be directly afflicted by the running of the first;
appearing as a perceived performance issue with stuttering display.
Fix the vsp1_dl_list_hw_update_pending() call to ensure that the read
comparison corresponds to the correct pipeline.

The media.h public header is very messy. It mixes legacy and 'new' defines
and it is not easy to figure out what should and what shouldn't be used. It
also contains confusing comment that are either out of date or completely
uninteresting for anyone that needs to use this header.
The patch groups all entity functions together, including the 'old' defines
based on the old range base. The reader just wants to know about the available
functions and doesn't care about what range is used.
All legacy defines are moved to the end of the header, so it is easier to
locate them and just ignore them.
The legacy structs in the struct media_entity_desc are put under
also a much more effective signal to the reader that they shouldn't be used
compared to the old method of relying on '#if 1' followed by a comment.
The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header
in the legacy area. They are also dropped from intf_type() in media-entity.c.
All defines are also aligned at the same tab making the header easier to read.

We've added a quirk to enable the recent Lenovo dock support, where it
overwrites the pin configs of NID 0x17 and 19, not only updating the
pin config cache. It works right after the boot, but the problem is
that the pin configs are occasionally cleared when the machine goes to
PM. Meanwhile the quirk writes the pin configs only at the pre-probe,
so this won't be applied any longer.
For addressing that issue, this patch moves the code to overwrite the
pin configs into HDA_FIXUP_ACT_INIT section so that it's always
applied at both probe and resume time.
