[PATCH v2 3/3] arm64: dts: freescale: add ULP watchdog nodes for i.MX platforms

[alice.guo at oss.nxp.com]

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

Add new ULP watchdog device tree nodes across multiple i.MX SoC device
trees. These watchdog instances were previously missing from the device
trees. All nodes are added with status disabled by default and include
the bootph-all property.
