media: i2c: lt6911uxe: Fix Kconfig dependencies:

The new driver fails to build if I2C is disabled:

drivers/media/i2c/lt6911uxe.c:703:1: error: data definition has no type or storage class [-Werror]
  703 | module_i2c_driver(lt6911uxe_i2c_driver);

or if I2C is on but V4L2_CCI_I2C is not:

ERROR: modpost: "cci_write" [drivers/media/i2c/lt6911uxe.ko] undefined!
ERROR: modpost: "cci_read" [drivers/media/i2c/lt6911uxe.ko] undefined!

For both by adding a dependency on I2C and selecting V4L2_CCI_I2C, which
follows the common practice for these.
