Some updates and initial improvements for the VSP1 partition algorithm that remove redundant processing and variables, reducing the processing done in interrupt context slightly.
Patch 1 brings in some protection against invalid pipeline configurations that are not supported by the partition algorithm on Gen3 hardware. Patches 2,3 and 4 clean up the calculation of the partition sizes such that they are only calculated once at streamon - and the partition windows are stored in the vsp1_pipeline object.
