media: i2c: ov5670: Support single-lane operation

Browse source

Currently the driver always configures the sensor for dual-lane MIPI
output, but it also supports single-lane output. Add support for that by
checking the data-lanes fwnode property how many lanes are used and
configure the necessary registers based on that.

To achieve this we move setting register 0x3018 out of the general reg
sequence so we set it to the correct value. The pixel_rate value also
needs to be adjusted.
