This patch adds mlp device to dtsi files for R-Car Gen3 SoCs that have
it.

v2: https://lore.kernel.org/lkml/20211226153349.2296024-1-nikita.yoush@cogentembedded.com/
Changes from v2:
- no longer part of patchset - other parts already merged
- add per-SoC compatible strings
- add resets
- keep only two interrupts - those used by the driver

v1: https://lore.kernel.org/lkml/20211226082530.2245198-4-nikita.yoush@cogentembedded.com/
Changes from v1:
- fix power domain ids so all dtbs build properly

i.e. will queue in renesas-devel for v5.18.

Note that as this device has no DT binding documentation, and the driver
is under staging, this can not be considered stable.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
