    drm/i915: restore ggtt double-bind avoidance

we wrote the ggtt_bind_vma() observing a number of cleanups we could do
over the template of aliasing_gtt_bind_vma(). Now let's apply the
cleanups we made there back to the original. The essence is to avoid
redundant variables and assignements, and by doing so make the code
easier to read.

In order for VLV and CHV to use i9xx_crtc_compute_clocks(), a number
of if ladders is necessary: one for setting the find_dpll() hook, one
for choosing the limits struct, one for choosing the right compute dpll
function and one for initializing the crtc_compute_clock() hook.

By extracting a platform specific implementation for each platform, the
number of if-ladders is reduced to one.

While at it also clean up bxt_find_best_dpll() which depends on some of

At the end of an atomic commit, we currently wait for vblanks to
complete, call put() on the various runtime PM references, and then try
to optimize our watermarks (on platforms that need two-step watermark
programming).  This can lead to watermark registers being programmed
while the power well is powered down.  We need to wait until after
watermark optimization is complete before dropping our runtime power
references.

Note that in the future the watermark optimization is probably going to
move to an asynchronous workqueue task that happens at some arbitrary
point after vblank.  When we make that change, we'll no longer
necessarily be operating under the power reference held here, so we'll
need to wrap the watermark register programmin in a call to
intel_runtime_pm_get_if_in_use() or similar.
