msm_fb: add quickdraw COORD_NO_OVERRIDE definition

This definition (0xFFFF) is used during a QuickDraw to indicate that we
should use the pre-defined coordinates in the buffer structure. If any
other value is used, the value defines panel (x,y) coordinates to draw the
buffer at. This has the inherit restriction that a buffer can't be drawn
at (-1,-1).
