Existing code is simply setting fb src position and plane crtc position to 0s (top left)
and src size as fb size and crtc size as plane size to start a fb with a plane. Then individual
test can change them to whatever fb position/size and plane position/size as it wants.
As I commented to 3/4 patch, if these initializations are removed, then all tests to be
updated to explicitly set them.

As a side note, is there any reason for having two patches 2/4 and 3/4 modifying
same lines of code instead of a single patch?
