[PATCH 7/8] arm64: dts: s32g3: Add the Software Timer Watchdog (SWT) description

[Daniel Lezcano]

Referred in the documentation as the Software Timer Watchdog (SWT),
the s32g3 has 12 watchdogs. The number of watchdogs is designed to
allow dedicating one watchdog per Cortex-M7/A53 present on the SoC.

Describe them in the device tree.
