dt-bindings: timer: Convert faraday,fttmr010 to DT schema

Convert the Faraday fttmr010 Timer binding to DT schema format. Adjust
the compatible string values to match what's in use. The number of
interrupts can also be anywhere from 1 to 8. The clock-names order was
reversed compared to what's used.
