Doh, it look me ages to see why - CPU ports have a different default which was what broke things for me. Makes the approach of having a default in coreboot a very good idea!

Hello Dinesh Gehlot, Kapil Porwal, Lean Sheng Tan, Matt DeVillier, Nick Vaccaro, Subrata Banik, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/81638?usp=email
to look at the new patch set (#8).
The following approvals got outdated and were removed:
Verified+1 by build bot (Jenkins)
Change subject: intel/alderlake: Add helper functions for Power Management
......................................................................
intel/alderlake: Add helper functions for Power Management
Clock Power Management, ASPM and L1 Substates have been
configured the same way since SkyLake. The main control to
enable or disable is Kconfig, and then the level can be overridden
in devicetree.
Despite the UPDs remaining the same since Skylake, this is not the
case for AlderLake, RaptorLake and MeteorLake.
Taking `starlabs/starbook` as an example, at the time of this
commit it has PCIEXP_CLK_PM, PCIEXP_ASPM and PCIEXP_L1_SUB_STATE
enabled.
On CometLake, this results in the correct configuration, verified
with the lspci command:
```
LnkCap: Port #0, Speed 5GT/s, Width x1, ASPM L1, Exit Latency L1 <8us
ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
ExtSynch- ClockPM+ AutWidDis- BWInt- AutBWInt-
```
On RaptorLake:
```
LnkCap: Port #0, Speed 16GT/s, Width x4, ASPM L1, Exit Latency L1 <64us
ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
```
Clock Power Management, ASPM and L1 Substates are also not configured
for CPU root ports.
Add helper functions to configure these correctly based on Kconfig, but
retain the capability to override the specific levels from devicetree.

Makefile.mk: Compress DSDT file with LZMA
Now that x86 has a CBFS cache we can use that cache as a DSDT ACPI table
decompression location. To be on the safe side, increase the cache size
to 64K which would largely fit all dsdt in coreboot.
