dt-bindings: timer: Convert Allwinner A10 Timer to a schema
The older Allwinner SoCs have a Timer supported in Linux, with a matching
Device Tree binding.
While the original binding only mentions one interrupt, the timer actually
has 6 of them.
Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
