After the commit below the Broxton PLL IDs had an off-by-one error, so
fix this up. Also add a missing brace at intel_shared_dpll_init(), it
happened to compile only due to the way the IS_BROXTON macro is defined.

v2:
- remove debugging left-over

Whenever there's an update to the primary plane,
fbc_pre_update and fbc_post_update are called. Kill off
intel_crtc->atomic.update_fbc and now that intel_crtc->atomic
is empty, kill it off too.

- Add a intel_fbc_supports_rotation helper.
Changes since v2:
- Remove intel_fbc_supports_rotation_helper.
- Remove unrelated changes.

fb_bits is useful to have in the crtc_state for cs flips when
the code is updated to use intel_frontbuffer_flip_prepare/complete.
So calculate it in advance and move it to crtc_state. The other stuff
can be calculated in post_plane_update, and aren't useful elsewhere.

Changes since v1:
- Changing wording, remove comment about loop.
Changes since v2:
- Rebase.

gcc-6 warns about code in the nouveau driver that is obviously silly:

drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
  if (pm->sequence != pm->sequence) {

The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.

This patch restores the original behavior.

The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D.  Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.

This class supports a WFI method (0x0078) that's not present on the
KeplerChannelGpfifoA class.

The binary driver exposes both classes on these GPUs for some reason,
though there doesn't appear to be any difference in the setup that's
done for each (ie. even if you allocate GpfifoA, the WFI method will
still work).

We shall just expose GpfifoB, as I don't see a good reason to report
the presence of both.
