Subject: [PATCH 4/8] arm64: dts: s32g399a-rdb3: Enable the STM timers

Enable the timers STM0 -> STM6, STM8 on the s32g399a-rdb3.

The platform has 8 CPUs and the Linux STM timer driver is per
CPU. Enable 8 timers which will be used, other timers are useless for
the Linux kernel and there is no benefit to enable them.

The STM7 is skipped as it is slightly different and needs an extra
property to be handled by the driver.
