Currently, the driver is working on the assumption that an I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using tvp514x_reg as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data() and simplifly probe(). While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.

This slightly increases the size of tvp514x_driver on non-OF system and shouldn't be an issue. Add mod_devicetable.h include. It also allows, in case if needed, to enumerate this device via ACPI with PRP0001 magic.
