Convert ptp-qoirq from txt to yaml format.

Additional change:
- Fixed example interrupts proptery. Need only 1 irq by check MPC8313 spec.
- Move Reference clock context under clk,sel.
- Interrupts is not required property.
- Use low case for hex value.
- Check reference manual of MPC8313, p1010 and so on, which dts use more
than 1 irqs. Only 1 irq for each ptp device. Check driver code
(drivers/ptp/ptp_qoriq.c) and only 1 irq used. So original description is
wrong.
- Remove comments for compatible string.
