arm64: dts: renesas: Enable IPMMU devices

[PATCH 01/04] arm64: dts: renesas: r8a7795: Enable IPMMU devices
[PATCH 02/04] arm64: dts: renesas: r8a7796: Enable IPMMU devices
[PATCH 03/04] arm64: dts: renesas: r8a77970: Enable IPMMU devices
[PATCH 04/04] arm64: dts: renesas: r8a77995: Enable IPMMU devices

Following the policy of using DT to describe the hardware and not software
support state, this series makes sure all IPMMU devices are enabled in DT
for SoCs such as r8a7795, r8a7796, r8a77970 and r8a77995.

Good policy! So "[PATCH 0/2] arm64: dts: renesas: r8a77970: Add SMP Support"

Thanks, I applied this by hand as the node order was changed by a
patch I queued up earlier today. The result is as follows:

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

Remove 'status = "disabled"' to make sure all IPMMU devices are enabled
in DT on the r8a77970 SoC.

Thanks, I applied this by hand as the node order was updated by
a patch that I applied earlier today. The result is as follows:

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

Remove 'status = "disabled"' to make sure all IPMMU devices are enabled
in DT on the r8a77995 SoC.
