Re: [PATCH v6 10/16] soc: mediatek: add mtk-mutex support for mt8195 vdosys1

Add mtk-mutex support for mt8195 vdosys1.
The vdosys1 path component contains ovl_adaptor, merge5,
and dp_intf1. Ovl_adaptor is composed of several sub-elements,
so change it to support multi-bit control.

This patch doesn't only add support for MT8195 vdosys1, but also changes
all definitions to a different "format", and also changes the type for
"mutex_mod" from int to long.
In reality, the actual functional change is minimal, compared to the size of
this entire patch.

Please, split this patch in two parts: one patch changing the defines and
the mutex_mod type (specifying that it's a preparation for adding support for
mt8195 vdosys1 mutex) and one patch adding such support.

Thanks!
