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/core: Change declaration for gamma_set. Change return value to int to propagate errors from gamma_set, and remove start parameter. Updates always use the full size, and some drivers even ignore the start parameter altogether. This is needed for atomic drivers, where an atomic commit can fail with -EINTR or -ENOMEM and should be restarted. This is already and issue for drm_atomic_helper_legacy_set_gamma, which this patch fixes up. Changes since v1: - Fix compiler warning.

drm: Add acquire ctx to ->gamma_set hook Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.
