From: Magnus Damm <damm+renesas@opensource.se>

Match on the r8a77965 SoC in the IPMMU driver. Software wise the same
IPMMU driver can be used as for other R-Car Gen3 SoCs, however the
hardware contains certain changes so using separate SoC compat strings
will allow us more fine grained control of features in the future.
