ARM: dts: meson8: add the ARM TWD timer
The Meson8 and Meson8m2 SoC are using four ARM Cortex-A9 cores which
come with a "TWD" (Timer-Watchdog) based timer. This adds support for
the ARM TWD Timer on these two SoCs.
Suggested-by: Carlo Caione <carlo@endlessm.com>
[ rebased patch from Carlo, use IRQ_TYPE_EDGE_RISING instead of
IRQ_TYPE_LEVEL_LOW to prevent "GIC: PPI13 is secure or misconfigured"
message during boot, use pre-processor macros to specify the IRQ,
added the correct clock, dropped TWD watchdog node since there's no
driver for it anymore ]
