[patch] video: fix SOC_CAMERA_MT9M001 build bug

[Ingo Molnar <mingo@elte.hu>]

on latest -git, with this config:

  http://redhat.com/~mingo/misc/config-Mon_Apr_28_13_25_34_CEST_2008.bad

  CONFIG_SOC_CAMERA_MT9M001=y
  CONFIG_SOC_CAMERA_MT9V022=y
  # CONFIG_I2C is not set

the build fails:

drivers/built-in.o: In function `reg_read':
mt9m001.c:(.text+0x140a87): undefined reference to `i2c_smbus_read_word_data'

drivers/built-in.o: In function `mt9v022_mod_exit':
mt9v022.c:(.exit.text+0x1666): undefined reference to `i2c_del_driver'

adding the missing I2C dependency fixes it.
