[PATCH] [media] davinci: add i2c Kconfig dependencies

[Arnd Bergmann]

All the davinci media drivers are using the i2c framework, and
fail to build if that is ever disabled, e.g.:

media/platform/davinci/vpif_display.c: In function 'vpif_probe':
media/platform/davinci/vpif_display.c:1298:14: error: implicit declaration of function 'i2c_get_adapter' [-Werror=implicit-function-declaration]

This adds explicit Kconfig dependencies so we don't see the
driver options if I2C is turned off.

This is a very rare randconfig error, normally I2C is enabled for some reason
already.
