[PATCH v8 1/3] dt-bindings: adc-joystick: add poll-interval

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

Add poll-interval support for the adc-joystick documentation. This is
an optional value and if not provided the adc-joystick works as it
does today (with buffers). If this value is provided, the adc-joystick
driver is polled at the specified interval. The existing attribute of
"poll-interval" was used instead of complying with property-units.yaml
after discussion of the issue on the mailing list.
