dt-bindings: arm: sp810: convert to DT schema

Browse source

The Arm SP810 IP is a "system controller", providing clocks, timer and a
watchdog.

Convert the DT binding to DT schema, to allow automatic validation.

The existing .txt binding described all properties as required, but the
assigned-clock* and clock-output-names are actually not (from a hardware
perspective). The only existing driver I could find (in Linux) doesn't
require them either, so drop those properties from the "required" list.
