shmem_pin_map somewhat awkwardly reimplements vmap using
alloc_vm_area and manual pte setup. The only practical difference
is that alloc_vm_area prefeaults the vmalloc area PTEs, which doesn't

To prepare for a follow-up LTTPR change factor out a helper to disable
the training pattern in DPCD. We'll need to do this for each LTTPR
(without programming the port to output the idle pattern) when training
in LTTPR non-transparent mode.
While at it also move the disable-link-training logic fro
This patchset is v2 of [1], addressing the comments from Ville and an
issue in the last patch with the per-PHY capability readout (needs to be
done after switching to non-transparent mode).

The DP Standard's recommendation is to use the LTTPR non-transparent
mode link training if LTTPRs are detected, so let's do this.
Besides power-saving, the advantages of this are that the maximum number
of LTTPRs can only be used in non-transparent mode (the limit is 5-8 in
transparent mode), and
By default LTTPRs should be in transparent link training mode,
nevertheless in this patch we switch to this default mode explicitly.
The DP Standard recommends this, supposedly because an LTTPR may be left
in the non-transparent mode (by BIOS, previous kernel, or after reset
due to a firmware bug)
Add the helpers and register definitions needed to read out the common
and per-PHY LTTPR capabilities and perform link training in the LTTPR
non-transparent mode.
v2:
- Add drm_dp_dpcd_read_phy_link_status() and DP_PHY_LTTPR() here instead
of adding these to i915. (Ville)

Reduce this maintenance nightmare a bit by converting the plane
min/max width/height stuff into vfuncs.
Now, if I could just think of a nice way to also use this for
intel_mode_valid_max_plane_size()...

Implement display w/a #1142. This supposedly fixes some underruns
with FBC+VTd. Bspec says we should use the same programming regardless
of circumstances. Apparently we should flip the magic bits before
turning on any planes so let's put this into the early w/as.
