media: atomisp: Take minimum padding requirement on BYT/ISP2400 into account

Browse source

The main binary for the pipeline on BYT/ISP2400 has its
ia_css_binary_info.pipeline.left_cropping and .top_cropping fields
set to 12. So a minimum padding of 12 is required.

And for certain bayer-orders additional width / height padding is
necessary so that the ISP crop rectangle for the raw sensor data
can be used to change the bayer-order to the fixed bayer-order
supported by the debayer block.

Without the minmum required padding ia_css_ifmtr_configure() will fail
inside ifmtr_input_start_line() and/or ifmtr_start_column() because
it cannot set the ISP crop rectangle for the raw sensor data.

Fix this by making atomisp_get_padding() take the minimum padding
requirements into account on BYT/ISP2400 (CHT/ISP2401 does not seem to
need this).
