Add the RPC HyperFlash device node along with its partitions to the
common ULCB 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.
