Merge tag 'renesas-soc-for-v4.18' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc

Renesas ARM Based SoC Updates for v4.18

* SoC
  - Change platform dependency to ARCH_RENESAS
    This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near
    future.
  - Add the to Kconfig RZ/N1D (r9a06g032) SoC
  - Identify R-Car E3 (r8a77990) SoC
  - Identify and add minimal support for RZ/G1C (r8a77470) SoC

* R-Car SYSC
  - Add support for R-Car E3 (r8a77990) SoC
  - Remove unused inclusion of <linux/sys_soc.h>,
  - Make r8a77995_areas[] const.

* R-Car Reset
  - Add support for R-Car E3 (r8a77990) SoC

* Debug-LL
  - Add support for RZ/G1C (r8a77470) SoC

* tag 'renesas-soc-for-v4.18' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  soc: renesas: r8a77990-sysc: Add workaround for 3DG-{A,B}
  soc: renesas: rcar-sysc: Add support for R-Car E3 power areas
  arm: shmobile: Add the RZ/N1D (R9A06G032) to the shmobile Kconfig
