drm/i915: grab the audio power domain when enabling audio on HSW+
With the current code, we unconditionally touch
HSW_AUD_PIN_ELD_CP_VLD, which means we can touch it when the power
well is off, and that will trigger an "Unclaimed register" message.
Just adding the intel_crtc->config.has_audio should already avoid the
unclaimed register messsages, but since we actually need the power
well to make the Audio code work, it makes sense to also grab the
audio power domain reference, and release it when it's not needed
anymore.
I used IGT's pm_rpm to reproduce this bug, but it can probably be
reproduced on other tests that do modesets. I'm using a machine with
eDP+HDMI connected.

drm/i915: Fix dynamic allocation of physical handles
A single object may be referenced by multiple registers fundamentally
breaking the static allotment of ids in the current design. When the
object is used the second time, the physical address of the first
assignment is relinquished and a second one granted. However, the
hardware is still reading (and possibly writing) to the old physical
address now returned to the system. Eventually hilarity will ensue, but
in the short term, it just means that cursors are broken when using more
than one pipe.
v2: Fix up leak of pci handle when handling an error during attachment,
and avoid a double kmap/kunmap. (Ville)
Rebase against -fixes.
v3: And fix the error handling added in v2 (Ville)
