ARM: OMAP2+: AM43x: basic dt support
Describe minimal DT boot machine details for AM43x based SoC's. AM43x SoC's are ARM Cortex-A9 based with one core. AM43x is similar to AM335x w.r.t L4 PER/WKUP memory map. AM43x has a sync timer, here that is being used as clocksource, while 1ms dmtimer as clockevent.
