Current auto select format start with the highest priority format and
gradually add lower priority formats one by one, and search matched
format. Like A+X -> A+B+X -> A+B+C+X+Y... (a)

But in this method, we can't handle format if HW has some kind of
patterns, like A+X or B+Y etc (b).

Current drivers are using (a) style, this patch switch to use (b) style.
This is needed before update auto select format method.
