Merge tag 'renesas-arm64-dt2-for-v4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

Second Round of Renesas ARM64 Based SoC DT Updates for v4.19

Corrections:

* Remove non-existing STBE region from Ether-AVB node in DT of
  R-Car E3 (r8a77990) SoC

Cleanups:

* Consistently use rwdt as label for Renesas Watchdog Timer devices
* Add second port to rcar_sound placeholder in DT of R-Car M3-N (r8a77965) SoC
* Fix adv7482 decimal unit addresses in DT of Salvator-X and -XS boards

Enhancements:

* Describe in DT:
  - INTC-EX of R-Car V3H (r8a77980) SoC
  - USB3.0 of R-Car E3 (r8a77980) SoC
  - All SCIF and HSCIF devices of R-Car D3 (r8a77995) SoC.
    Previously only SCIF2, used as the debug consile, was described.
  - All IPMMU devicesof R-Car M3-N (r8a77965), V3H (r8a77980) and
    E3 (r8a77990) SoCs
* Enable USB3.0 in DT of R-Car E3 (r8a77980) based Ebisu board
* Prefer HSCIF1 over SCIF1 in DT of Salvator-X and -XS boards
