skl_calc_main_surface_offset() is used to calculate an aligned plane surface address considering the inner framebuffer x and y offset. It can not be used by selective fetch functions becase there is no PLANE_SEL_FETCH_SURF. So the PLANE_SEL_FETCH_OFFSET.y should only be PLANE_OFFSET.y + damaged_area_within_plane.y1.
This fixes glitches seen in fbcon caused by typing something in the terminal.
