Please note that since Linux commit:
"9c9f7891093b02eb64ca4e1c7ab776a4296c058f soc: renesas: Identify R-Car
M3-W+"
the compatible string for R-Car M3-W+ (ES3.0) SoC is "renesas,r8a77961". So
in case we want to have vSCMI feature on this new SoC revision as well we
will need
to extend the compatible list.
