ASoC: dt-bindings: realtek,rt5640: Make interrupts optional

The RT5640 GPIO1/IRQ pin can be configured either as GPIO1 or as the
codec interrupt output.

Some boards, such as the Firefly-RK3399, do not connect the codec
interrupt output. This causes the following binding validation warning:

'interrupts' is a required property

Make the interrupts property optional to support such hardware
configurations.
