[PATCH v2 3/9] dt-bindings: input: microchip,cap11xx: Update datasheet URL and LED reg range

[Jun Yan]

- Add datasheet links for all supported CAP11xx variants.
- Update LED node regex and replace enum constraints with minimum/maximum
  for LED reg ranges in preparation for CAP1114 support.

CAP1114 has 11 LED channels. minimum/maximum constraints are easier to
maintain than long enum lists when expanding channel count later.
