[PATCH v2] arm: dts: imx8ulp: Update device tree to fix boot issue on i.MX8ULP EVK

[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.

The driver model for watchdog timer is not enabled yet, so disable wdog3
temporarily.
