Subject: [PATCH] TTP229-LSF i2c device support (#489)

* setting up non i2c ttp229

* add component

* fixed const and multiconf

* fixed issues with i2c address (it is fixed for this device
renamed component and platform to ttp229_lsf => i2c device. There is
another ttp229_bsf device that uses a proprietary bus protocol

* max channels is 0 to 15

* folow up on code review

* fixed Component ttf229_lsf
