arm64: dts: s32g2: Add the Software Timer Watchdog (SWT) nodes

Browse Source 
Referred in the documentation as the Software Timer Watchdog (SWT),
the s32g2 has 7 watchdogs. The number of watchdogs is designed to
allow dedicating one watchdog per Cortex-M7/A53 present on the SoC.

Add the SWT nodes in the device tree.
