defconfig: apq8084: Disable bayer camera drivers

This change is required to disable the IMX132, IMX135
image sensor drivers compilation for apq8084 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.
