Subject: [PATCH v2 2/7] media: ipu3-cio2: Set valid initial format

The initial format did not have a valid size.

Fixes v4l2-compliance:

fail: v4l2-test-formats.cpp(723): Video Output Multiplanar:
				  TRY_FMT(G_FMT) != G_FMT
test VIDIOC_TRY_FMT: FAIL

Signed-off-by: Ricardo Ribalda <ribalda@...omium.org>

v2: Suggested by Sakari Ailus <sakari.ailus@...ux.intel.com>

Replace number with calculation based on width.
