hwc: regionizer: Batch flags fixes

+ Removed BVBATCH_DST since the destination parameters (buffdesc
  and geometry) are not changing while performing blending within
  a batch.
+ Removed BVBATCH_SRC2RECT_SIZE, the rectangle size never changes
  while constructing blits within a horizontal subregion.
+ Added BVBATCH_SRC1RECT_ORIGIN, it's highly possible the src1 origin
  changes from a previous blit within the batch, a good example is the
  volume pop blended on top of the widget and wallpaper layers in the
  Android homescreen.

This change doesn't address batch flags while scaling, those will
be revisited later when the GC driver supports it.
