dt-bindings: timer: Add compatible for am6 for TI timer-dm

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs.
As the timer hardware is the same between am64, am65 and j72 we use the
compatible name for the earliest SoC with this timer.

The timer interrupts are not routable for the operating system for some
timers on am6. Let's make sure the interrupts are configured for the
timers on all other SoCs.
