gpu: ipu-v3: image-convert: fix bytesperline adjustment

For planar formats, bytesperline does not depend on BPP. It must always
be larger than width and aligned to tile width alignment restrictions.

The input bytesperline to ipu_image_convert_adjust() may be
uninitialized, so don't rely on input bytesperline as the
minimum value for clamp_align(). Use 2 << w_align as the minimum
instead.
