[PATCH 4/5] arm64: dts: renesas: salvator-common: Add RPC HyperFlash device node

[Geert Uytterhoeven]

Add the RPC HyperFlash device node along with its partitions to the
common Salvator-X(S) board DTS file.

Based on a patch in the BSP by Valentine Barshak.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

Changes compared to the BSP:
  - Update label,
  - Keep RPC disabled,
  - Add missing "cypress,hyperflash" compatible value,
  - Drop leading zeroes from unit addresses,
  - Use lower-case hexadecimal values,
  - Enlarge uboot partition,
  - Drop uboot-env partition.
