Serge Semin e69bc89996 dt-bindings: timer: Move snps,dw-apb-timer DT schema from rtc
This binding file doesn't belong to the rtc seeing it's a pure timer
with no rtc facilities like days/months/years counting and alarms.
So move the YAML-file to the Documentation/devicetree/bindings/timer/
directory.

with the picoxcell platform.
