[v1,0/8] MediaTek mmsys/mutex fixes and improvements

Message

This series adds the missing DPI1 SOF/EOF to the MT8188 mutex tables,
required to support output through DPI1->HDMI Transmitter, and also
adds a few fixes and improvements to the mtk-mmsys driver and tables
for all SoCs.
For MT8188, in MMSYS, this adds the DSC path for the display
controller, and fixes the current DPI1 one to actually do something
meaningful... and speaking of mmsys....

In particular, since I've found multiple basic mistakes in the mmsys
tables for more than one SoC, I've identified a strong need to do
something to prevent that from happening again in the future.

That was done by adding a macro that performs a compile time check
to make sure that the in/out selection bits do actually fit in the
register mask, and converting all of the current mmsys drivers to
use it (because pre-existing code is usually taken as reference to
write new one... hopefully!!!!!).

Of course, the fixes that I performed to the MT8167/MT8365 are
relative to issues found while converting their mmsys tables to
the new macro... :-)
