[PATCH 7/8] dt-bindings: input: microchip,cap11xx: Add CAP1114 support

[Jun Yan <jerrysteve1101@gmail.com>]

CAP1114 is a 14-channel capacitive touch sensor with 11 LED outputs
and hardware reset support.

Add the compatible string for CAP1114, include its datasheet URL,
and update the maximum count of LED channels and linux,keycodes entries.

Add description for microchip,input-threshold: CAP1114 only provides eight
threshold entries, which does not match its total channel count.
