[PATCH v1 06/10] imx93: dtsi: Add wdog3/wdog4/wdog5 alias and bootph-all property

[alice.guo at oss.nxp.com]

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

Introduce wdog3, wdog4, and wdog5 aliases and mark the corresponding
nodes with bootph-all to enable imx_wdog_alias_to_addr() to resolve the
watchdog register base addresses via the device tree.

When CONFIG_OF_UPSTREAM is disabled, upstream device tree files are not
used. Therefore, wdog4 and wdog5 nodes need to be added directly to
arch/arm/dts/imx93.dtsi.
