dt-bindings: timer: via,vt8500-timer: Convert to YAML 



Rewrite the textual description for the VIA/WonderMedia timer
as YAML schema.

The IP can generate up to four interrupts from four respective match
registers, so reflect that in the schema.

title: VIA/Wondermedia VT8500 Timer



description:

  This is the timer block that is a standalone part of the system power

  management controller on VIA/WonderMedia SoCs (VIA VT8500 and alike).

  The hardware has a single 32-bit counter running at 3 MHz and four match

  registers, each of which is associated with a dedicated match interrupt,

  and the first of which can also serve as the system watchdog (if the

  watchdog function is enabled, it will reset the system upon match instead

  of triggering its respective interrupt)
