The sensor driver sets mbus format colorspace information and sizes,
but not ycbcr encoding, quantization and xfer function. When supplied
with an badly initialized mbus frame format structure, those fields
need to be set explicitly not to leave them uninitialized. This is
tested by v4l2-compliance, which supplies a mbus format description
structure and checks for all fields to be properly set.

Without this commit, v4l2-compliance fails when testing formats with:
fail: v4l2-test-formats.cpp(335): ycbcr_enc >= 0xff
