    Input: ads7846 - use spi_device_id table
    
    [ Upstream commit 7c7b1be19b228b450c2945ec379d7fc6bfef9852 ]
    
    As the driver supports more devices over time the single MODULE_ALIAS
    is complete and raises several warnings:
    SPI driver ads7846 has no spi_device_id for ti,tsc2046
    SPI driver ads7846 has no spi_device_id for ti,ads7843
    SPI driver ads7846 has no spi_device_id for ti,ads7845
    SPI driver ads7846 has no spi_device_id for ti,ads7873
    
    Fix this by adding a spi_device_id table and removing the manual
    MODULE_ALIAS.
