Renaming the HSW-specific macros for ddi buffer translation slot to denote the
slot and not the vswing/pre-emph values as they are platform-dependent.
This patch is based on top of the patch series for renaming the DP training

Previously, it was possible for the GPU memory accesses to be swizzled
to try to optimize the fetches for tiled buffers. This swizzling was on
top of what the memory controller in the uncore already does.
With broadwell, we drop that GPU side swizzling, and the corresponding
initialization in 3 units (GAM, GT, DE). All those bits are reserved, as
specs put it:
Before Gen8, there was a historical configuration control field to
swizzle address bit[6] for in X/Y tiling modes. This was set in three
different places: TILECTL[1:0], ARB_MODE[5:4], and
DISP_ARB_CTL[14:13]"
For Gen8 the swizzle fields are all reserved, and the CPU's memory
controller performs all address swizzling modifications.
This also means that user space doesn't have to manually swizzle when
accessing tiled buffers from the CPU, and so we always return
I915_BIT_6_SWIZZLE_NONE from i915_gem_detect_bit_6_swizzle(), which
short-circuits the initialization of the registers mentionned above in
i915_gem_init_swizzling().

On BDW we're seeing a problem that after we runtime resume, the
outputs connected to DDI C are not detected: they don't appear in the
SDEISR register and GMBUS transactions don't work. They stop working
at the moment we call intel_opregion_notify_adapter() during runtime
suspend, but they don't go back to work when we call the same function
during runtime resume. They only work after we do a modeset and call
intel_opregion_notify_encoder(), but this point is already too late.
While debugging, I tried to pass PCI_D3hot which is the value that
matches the spec, and it seems to have solved the problem. I couldn't
find any explanation of why this solves the problem, but there's also
no documented explanation - besides our code and git log - of why
Haswell should use PCI_D1, so keep this for now in order to keep BDW
runtime PM working.
Also add a comment to point the fact that there's no spec documenting
all the weirdness involved here.

Unfortunately, the gem_obj/vma relationship is not symmetrical; a gem_obj
can look up for the same vma more than once (where the ppgtt refcount is
incremented), but will free the vma only once (i915_gem_free_object).
This difference in refcount get/put means that the ppgtt is not removed
after the context and vma are destroyed, because sometimes the refcount
will never go back to zero.
v2: Just move the ppgtt refcount into vma_create.
