[PATCH v2 2/5] arm: dts: imx: Update watchdog nodes for dynamic base address lookup

[alice.guo at oss.nxp.com]

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

Update watchdog device tree nodes to enable dynamic base address
retrieval for i.MX7ULP, i.MX8ULP, i.MX91, i.MX93, i.MX943, i.MX95 and
i.MX952. This allows the bootloader to obtain watchdog base addresses
from the device tree instead of using hardcoded values.

- imx7ulp: Add wdog2 node
- imx8ulp: Mark wdog3 available
- imx91/imx93: Add wdog4 and wdog5 nodes
	       Mark wdog3/wdog4/wdog5 available
- imx943: Add wdog4 node and mark wdog3/wdog4 available
- imx95/imx952: Add wdog4 node and mark wdog3/wdog4 available

Watchdog nodes are marked with "bootph-all" to ensure availability
during early boot stages when init_wdog() occurs.
