input: atmel_mxt_ts: Support runtime selection of config data
Add support for dynamic configuration data update if the target can
support more than one Atmel chip. Platform data contains an array of
supported config data along with family ID, variant ID and firmware
version. Driver searches for matching family ID, variant ID and
firmware version, and uses the corresponding config data to program.
