drm/i915 feature pull #2 for v6.9:

Features and functionality:
- DP tunneling and bandwidth allocation support (Imre)
- Add more ADL-N PCI IDs (Gustavo)
- Enable fastboot also on older platforms (Ville)
- Bigjoiner force enable debugfs option for testing (Stan)

Refactoring and cleanups:
- Remove unused structs and struct members (Jiri Slaby)
- Use per-device debug logging (Ville)
- State check improvements (Ville)
- Hardcoded cd2x divider cleanups (Ville)
- CDCLK documentation updates (Ville, Rodrigo)

Fixes:
- HDCP MST Type1 fixes (Suraj)
- Fix MTL C20 PHY PLL values (Ravi)
- More hardware access prevention during init (Imre)
- Always enable decompression with tile4 on Xe2 (Juha-Pekka)
- Improve LNL package C residency (Suraj)

drm core changes:
- DP tunneling and bandwidth allocation helpers (Imre)

* @intel_dp: Intel DP object
* @max_dprx_rate: Maximum data rate of the DPRX
* @max_dprx_lanes: Maximum lane count of the DPRX
*
* Data bandwidth is the actual payload rate, which depends on the data
* bandwidth efficiency and the link rate.
* Calculate the maximum data rate for the provided link parameters taking into
* account any BW limitations by a DP tunnel attached to @intel_dp.
*
* For 8b/10b channel encoding, SST and non-FEC, the data bandwidth efficiency
* is 80%. For example, for a 1.62 Gbps link, 1.62*10^9 bps * 0.80 * (1/8) =
* 162000 kBps. With 8-bit symbols, we have 162000 kHz symbol clock. Just by
* coincidence, the port clock in kHz matches the data bandwidth in kBps, and
* they equal the link bit rate in Gbps multiplied by 100000. (Note that this no
* longer holds for data bandwidth as soon as FEC or MST is taken into account!)
*
* For 128b/132b channel encoding, the data bandwidth efficiency is 96.71%. For
* example, for a 10 Gbps link, 10*10^9 bps * 0.9671 * (1/8) = 1208875
* kBps. With 32-bit symbols, we have 312500 kHz symbol clock. The value 1000000
* does not match the symbol clock, the port clock (not even if you think in
* terms of a byte clock), nor the data bandwidth. It only matches the link bit
* rate in units of 10000 bps.
* Returns the maximum data rate in kBps units.
