drm/gma500: Add page flip support on psb/cdv Legacy (non-atomic) page flip support is added to the driver by using the mode_set_base CRTC function, that allows configuring a new framebuffer for display. Since the function requires the primary plane's fb to be set already, this is done prior to calling the function in the page flip helper and reverted if the flip fails. The vblank interrupt handler is also refactored to support passing an event. The PIPE_TE_STATUS bit is also considered to indicate vblank on medfield only, as explained in psb_enable_vblank. It was tested by running weston on both poulsbo and cedartrail.

drm/gma500: make local header files more self-contained Add proper forward declarations to minimize dependencies on other header files. Just add enough that we can safely include all header files in alphabetically order in relevant files.
