ARM: dts: OMAP2+: Update DMTIMER compatibility property 

Update the DMTIMER compatibility property to reflect the register level
compatibilty between devices and update the various OMAP/AM timer
bindings with the appropriate compatibility string.

By doing this we can add platform specific data applicable to specific
timer versions to the driver. For example, errata flags can be populated
for the timer versions that are impacted.

OMAP Timer bindings
Required properties:
- compatible: Must be "ti,omap2-timer" for OMAP2+ controllers.
- compatible: Should be set to one of the below. Please note that
OMAP44xx devices have timer instances that are 100%
register compatible with OMAP3xxx devices as well as
newer timers that are not 100% register compatible.
So for OMAP44xx devices timer instances may use
different compatible strings.
ti,omap2420-timer (applicable to OMAP24xx devices)
ti,omap3430-timer (applicable to OMAP3xxx/44xx devices)
ti,omap4430-timer (applicable to OMAP44xx devices)
ti,omap5430-timer (applicable to OMAP543x devices)
ti,am335x-timer (applicable to AM335x devices)
ti,am335x-timer-1ms (applicable to AM335x devices)

length).
- interrupts: Contains the interrupt information for the timer. The
