61a60df627 drm/i915/audio: Hardware ELD readout 
Read out the ELD from the hardware buffer, or from our stashed
copy for the audio component, so that we can hook up the state
checker to validate it.

5d986635e2 drm/i915/audio: Precompute the ELD 
Stash the ELD into the crtc_state and precompute it. This gets
rid of the ugly ELD mutation during intel_audio_codec_enable(),
and opens the door for the state checker.

v2: Make another copy for the acomp hooks (Chaitanya)
    Split out the bogus ELD handling change (Jani)

112a87c48e drm/i915/display: program audio CDCLK-TS for keepalives 
XE_LPD display adds support for display audio codec keepalive feature.
This feature works also when display codec is in D3 state and the audio
link is off (BCLK off). To enable this functionality, display driver
must update the AUD_TS_CDCLK_M/N registers whenever CDCLK is changed.
Actual timestamps are generated only when the audio codec driver
specifically enables the KeepAlive (KAE) feature.

This patch adds new hooks to intel_set_cdclk() in order to inform
display audio driver when CDCLK change is started and when it is
complete.

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
