Add the bootph-all property to ULP watchdog nodes across multiple i.MX
SoC device trees, ensuring the watchdog is available during all boot
phases.
The affected watchdog nodes are:
- imx8ulp: wdog3
- imx91/93: wdog3, wdog4, wdog5
- imx94: wdog3
- imx95: wdog3
- imx952: wdog3

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.

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] Invalid full-width semicolon used to terminate the `bootph-all` property in `imx7ulp.dtsi`.
- [Low] Commit message prefix does not accurately reflect the changes.

commit bf6ac00d8852230a7eddc4b1f0a7d7bed4fb72cd
Author: Alice Guo <alice.guo@nxp.com>
arm64: dts: freescale: add ULP watchdog nodes for i.MX platforms
This commit adds ULP watchdog nodes to several i.MX device trees, bringing
in previously missing watchdog instances. All added nodes are disabled by
default and include the bootph-all property.
> arm64: dts: freescale: add ULP watchdog nodes for i.MX platforms
This isn't a bug, but the commit prefix specifically mentions arm64, while
the patch also modifies an arm 32-bit device tree in
arch/arm/boot/dts/nxp/imx/imx7ulp.dtsi. Would it be better to split this
into separate patches for each architecture, or adjust the prefix?

Does this property definition end with a full-width Unicode semicolon rather
than a standard ASCII semicolon? It appears this might lead to a syntax error
when the device tree compiler processes the file.
