arm64: dts: freescale: add bootph-all to watchdog nodes for i.MX platforms

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
