Subject: drm/omap: DISPC: support double-pixel mode

We need double-pixel mode (pixel repetition) for interlace modes. This
patch adds the necessary support to DISPC to output double-pixel mode.

Subject: drm/omap: DISPC: Fix field order for HDMI

Interlace field order is different between VENC and HDMI. The driver
currently sets the field order for VENC.

This patch adds the code to set the field order for HDMI.

Subject: drm/omap: Add dispc_mgr_get_supported_outputs()

We are removing the use of the 'struct omap_overlay_manager' from
omapdrm, and one part of that is removing the use of
mgr->supported_outputs field.

This patch adds dispc_mgr_get_supported_outputs() function which can be
used instead of mgr->supported_outputs. omap_crtc.c is changed to use
the new function.

Subject: drm/omap: remove dss compat code

We have removed all the uses of compat code from omapdrm and the
non-compat parts of omapdss, so now we can remove all the compat code
itself.
