We have a bunch of neat little macros all over the place which should
move to kernel.h. But some of them died in bikesheds on lkml, and we
need a decent home for them.
Start out by moving the for_each_if macro there.
v2: Rename to drm_util.h instead (Dave&Sean)

Add drm_encoder_mask() which returns the 1<<index for the encoder.
We already have an identical drm_crtc_mask() for crtcs.

Bake in the conflict between the drm_print.h extraction and the
addition of DRM_DEBUG_LEASES since we lost it a few too many times.
Also fix a new use of drm_plane_helper_check_state in msm to follow

The lease updates missed a few bits of docs, fixed up

Point at the equivalent atomic state and explain that atomic drivers
shouldn't really depend upon legacy state.
Motivated by questions from Manasi about how this all is supposed to
work.

The drm_crtc_mask() function used in <drm/drm_encoder.h> is a static
inline defined in <drm/drm_crtc.h>. If the first header is included in a
compilation unit without the second one, the following compilation
warning will be issued.
In file included from <linux>/drivers/gpu/drm/drm_bridge.c:29:0:
<linux>/include/drm/drm_encoder.h:192:95: warning: ‘drm_crtc_mask’ used but never defined
static inline uint32_t drm_crtc_mask(const struct drm_crtc *crtc);
Fix this by including the header defining the function instead of using
a forward declaration.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

Just for the struct drm_mode_object base class. The header file was
already partially extracted to help untangle the include loops.
v2:
- Also move the generic get/set property ioctls. At first this seemed
like a bad idea since it requires making drm_mode_crtc_set_obj_prop
non-static. But eventually that will get split away too (like
the connector version already is) for both crtc and planes. Hence I
reconsidered.
- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
renaming the drm_modeset.h header I already started building up.
This is more consistent (matches the name of the main structure),
and I want to be able to use drm_modeset.[hc] for the basic modeset
init/cleanup functionality like drm_mode_config_init.

- Move missing bits into struct drm_encoder docs.
- Explain that encoders are 95% internal and only 5% uapi, and that in
general the uapi part is broken.
- Remove verbose comments for functions not exposed to drivers.
v2: Review from Archit:
- Appease checkpatch in the moved code.
- Make it clearer that bridges are not exposed to userspace.

Same treatment as before. Only hiccup is drm_crtc_mask, which
unfortunately can't be resolved until drm_crtc.h is less of a monster.
Untangle the header loop with a forward declaration for that static
inline.
