[PATCH v3 1/2] arm: dts: imx8ulp: Ensure mu at 27020000 and lpuart5 availability during all boot phases

[alice.guo at oss.nxp.com]

From: Alice Guo <alice.guo at nxp.com>

mu at 27020000 is required for communication with ELE firmware, and
lpuart5 is the standard output device. Both peripherals must be
available before U-Boot relocation. Use bootph-all instead of
bootph-pre-ram so these nodes are retained across all boot phases.
