Input: cap11xx - add support for CAP1114

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

The CAP1114 uses two control registers for LED output management and
requires two button status registers for touch input state reporting.

By default, channels CS8~CS14 operate as a single grouped block.
Set the corresponding register enable bit to enable these channels as
independent touch inputs. Note these channels share the input threshold
of the eighth entry, causing num_sensor_thresholds to differ from
num_channels.
