fd1a9bba73 drm/i915: Convert bandwidth state to global state
Now that we have the more formal global state thing let's
use if for memory bandwidth tracking. No real difference
to the current private object usage since we already
tried to avoid taking the single serializing lock needlessly.
But since we're going to roll the global state out to more
things probably a good idea to unify the approaches a bit.

b42d3b159a drm/i915/display: cleanup intel_bw_state on i915 module removal
intel_bw_state allocated memory is not getting freed even after
module removal.

Call the drm_atomic_private_obj_fini(), which inturn calls the
intel_bw_destroy_state() to make sure the intel_bw_state memory is
freed properly.

366b6200f7 drm/i915/bw: make intel_atomic_get_bw_state() static
No need for this function to be accessible outside of intel_bw.c. Avoid
including the i915_drv.h mega header from other header files to make
further header cleanup easier.

df0566a641 drm/i915: move modesetting core code under display/
Now that we have a new subdirectory for display code, continue by moving
modesetting core code.

display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.

v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
