[PATCH 8/8] arm: dts: socfpga: rsu: Label boot partition for label-based lookup

[dinesh.maniyam at altera.com]

From: Dinesh Maniyam <dinesh.maniyam at altera.com>

rsu_dtb() locates the RSU-managed boot partition by scanning every
fixed-partitions node for the "Boot and fpga data" label, falling back
to the legacy rsu-handle phandle only when no label matches.

Relabel the Agilex5 SoCDK qspi_boot partition from "u-boot" to
"Boot and fpga data" so the primary label scan resolves on the local
DTB. The unrelated NAND "u-boot" partition is left untouched.
Stratix10 already carries the matching label (aligned with the upstream
Linux DTS), and the other SoC64 SoCDKs are not in mainline yet.

While here, drop the redundant fixed-partitions override from
socfpga_agilex_socdk-u-boot.dtsi: the Agilex SoCDK consumes its
devicetree from the upstream source tree, which already defines the
QSPI partitions, so the U-Boot overlay copy only risked drift.
