Subject: [PATCH v4] arm64: dts: agilex/stratix10: Updated QSPI Flash layout for UBIFS

From: Alif Zakuan Yuslaimi <alif.zakuan.yuslaimi@...el.com>

Non-UBIFS related boot and fpga data should be stored in qspi_boot (mtd0)
while keeping the rootfs with UBIFS in the root partition "mtd1".
Thus, update the QSPI flash layout to support UBIFS in the mtd root
partition.
