[PATCH 7/8] arm: dts: socfpga: rsu: Anchor RSU DM node across SoC64 families

From: Dinesh Maniyam <dinesh.maniyam at altera.com>
The RSU driver-model anchor ("altr,socfpga-rsu") is consumed only by the
U-Boot-proper console command, never by SPL. It was previously present
only for Agilex, via the socfpga-rsu node under soc at 0 in
socfpga_soc64_u-boot.dtsi.
The other SoC64 families assemble their devicetree under a "soc" node and
pull in only the FIT image overlay (socfpga_soc64_fit-u-boot.dtsi), which
carries no SoC nodes, so the anchor never reached them. With
CONFIG_SOCFPGA_RSU_DM=y that left rsu_init() returning -ENODEV on Agilex5,
Stratix10 and N5X even though the RSU command is enabled there.
Add the anchor node to the Agilex5, N5X and Stratix10 U-Boot devicetree
overlays, and drop bootph-all from the Agilex node so the anchor is not
carried into the pre-relocation/SPL devicetree; it is only needed by the
proper-only console command.
