commit 276739485501e61096034ec036337feab4c07dc5 upstream.

As per section 35.3.1 Starting Reception for the MIPI CSI-2 Input on the
latest hardware manual (R01UH0914EJ0140 Rev.1.40) it is mentioned that
initialize the AXI master first and then initialize the image processing.
Fix the start procedure as per the hardware manual.
