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.
