defconfig: msm8610: Disable bayer camera drivers

This change is required to disable the IMX134, OV9724,
OV5648, OV8825, s5k4e1, OV12830 image sensor drivers
compilation for msm8610 based platforms.

In current camera implementation we need to prevent twice
creating of kernel video nodes because this is already
done in "generic" sensor driver.
