Subject: media: omap3isp: set initial format

From: Hans Verkuil <hverkuil+cisco@kernel.org>

[ Upstream commit 7575b8dfa91f82fcb34ffd5568ff415ac4685794 ]

Initialize the v4l2_format to a default. Empty formats are
not allowed in V4L2, so this fixes v4l2-compliance issues:

	fail: v4l2-test-formats.cpp(514): !pix.width || !pix.height
test VIDIOC_G_FMT: FAIL
