dt-bindings: timer: Update TI timer to yaml
Let's update the TI timer binding to use yaml. As this binding is specific to the TI dual-mode timers also known as dm-timers, let's use file name ti,timer-dm.yaml to avoid confusion with other timers. We add checks for the deprecated ti,hwmods property as done for other TI device driver bindings earlier. We also correct the issue with the old binding that was out of date for several properties. The am43 related timers are undocumented, but compatible with the am3 timers. Let's add the am43 timers too. The dm814 and dm816 timers are missing, let's add them. Some timers on some SoCs are dual mapped, like the ABE timers on omap4 and 5. The reg property maxItems must be updated to 2. The timer clocks can be managed by the parent interconnect target module with no clocks assigned for the timer node. And in some cases, the SoC may need to configure additional system clock for the timer in addition to the functional clock. The clock names are optional and not specific to the comptible property. For example, dra7 timers on l3 interconnect do not need clock-names, while the timers on dra7 l4 interconnect need them with both being compatible with ti,omap5430-timer.
