drm/omap: move dispc related dss-feat funcs to dispc

omapdrm still uses a few non-dispc functions: dss_feat_get_num_mgrs(),
dss_feat_get_num_ovls() and dss_feat_get_supported_color_modes(). We
want to provide omapdrm a single dispc_ops function pointer struct so
that omapdrm will use either the current omapdss or the new omapdss6
driver depending on the platform.

Those three functions are really dispc functions, but are located in the
dss_features.c for legacy reasons.

This patch adds similar functionss to the dispc, and changes omapdrm to
use those new functions. Underneath the functions still call the
functions from dss_feature.c.

drm/omap: fix primary-plane's possible_crtcs

We set the possible_crtc for all planes to "(1 << priv->num_crtcs) - 1",
which is fine as the HW planes can be used fro all crtcs. However, when
we're doing that, we are still incrementing 'num_crtcs', and we'll end
up with bad possible_crtcs, preventing the use of the primary planes.

This patch passes a possible_crtcs mask to plane init function so that
we get correct possible_crtc.

drm/omap: print error instead of WARN() if plane setup fails

omap_plane_atomic_update() does WARN_ON() if dispc rejects the given
plane config. Change that to dev_err() to lessen the possible spam.

To fix this correctly, the plane setup needs much more work by creating
a check function for dispc setup, so that we could reliably check the
config in atomic_check, instead of only noticing the problem when
programming dispc.

drm/omap: fix plane check when crtc is disabled

I sometimes see:

which comes from drm_framebuffer_remove() when it's disabling the crtc
with zeroed drm_mode_set.

The problem in omap_plane_atomic_check() is that it will use those
zeroed fields to verify if the setup is correct.

This patch makes omap_plane_atomic_check() return 0 if the crtc is
