video: kconfig: remove DM_I2C dependency of I2C_EDID

Drop the DM_I2C dependency, as the library only implements
the parsing of EDID data and doesn't depend on any driver

One user of this library, the i2c command, implements
support for legacy and DM I2C drivers

Tested on a Zynq board, whose I2C driver is not ported
yet to DM
