Note: Apparently the master IPMMU instance has an interrupt bit number
in the MMU Interrupt Status Register, too. This is currently not
described in DT, as no renesas,ipmmu-main property is present for the
master instance. Currently this doesn't matter, as the driver doesn't
use the interrupt bits at all.
