[PATCH v3 0/9] imx: Switch watchdog addressing from macros to devicetree

[alice.guo at oss.nxp.com]

CI: https://github.com/u-boot/u-boot/pull/967/checks

The watchdog DT changes have already been posted to the upstream Linux
kernel, addressing the concern about avoiding unnecessary growth of
u-boot.dtsi. Linux DT changes are available at:
https://lore.kernel.org/all/20260512024850.904551-1-alice.guo@oss.nxp.com/T/#u

Changes for v2:
- Iterate all watchdog nodes in device tree instead of wdog alias
- Delete non-DM implementation of the ULP watchdog driver

Changes for v3:
- Convert imx7ulp, imx91, imx93-frdm and imx93_var_som to CONFIG_OF_UPSTREAM
