[PATCH v1 02/13] iio: adc: ti-tsc2046: Simplify device abstraction

[Uwe Kleine-König (The Capable Hub)]

The driver was introduced in 2021 and since then only supports a single
chip variant. Simplify the driver by hard-coding the device properties
instead of using the id_table's abstraction for a single chip type.
