[0/8] Enable LNL display

This series aims at providing the remaining patches for enabling display
on Lunar Lake, which used Xe2LPD display IP.

The first set of patches contains fixes and extra stuff required for
supporting CDCLK on Xe2LPD:

    drm/i915/cdclk: Rename lnl_cdclk_table to xe2lpd_cdclk_table
    drm/i915/cdclk: Add and use xe2lpd_mdclk_source_sel()
    drm/i915/cdclk: Only compute squash waveform when necessary
    drm/i915: Extract intel_dbuf_mdclk_cdclk_ratio_update()
    drm/i915: Add mdclk_cdclk_ratio to intel_dbuf_state
    drm/i915/xe2lpd: Support MDCLK:CDCLK ratio changes

Then we have a single patch that enables loading Xe2LPD DMC, which is
already available in linux-firmware:

    drm/i915/xe2lpd: Load DMC

Finally, we have the last patch, which enables display for LNL:

    drm/xe/lnl: Enable display support

I believe this last one is supposed to be merged via drm-xe-next.
