Attention is currently required from: Sean Rhodes, Matt DeVillier, Angel Pons.

Hello build bot (Jenkins), Matt DeVillier, Angel Pons, Eric Lai,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/72765

to look at the new patch set (#4).

Change subject: soc/intel/rtd3: Hook up supported states to Kconfig
......................................................................

soc/intel/rtd3: Hook up supported states to Kconfig

Report `4` in `_S0W` only when D3COLD_SUPPORT is enabled, as if it
is not, it will break S3 exit.

When D3COLD_SUPPORT is not enabled, return `3` (D3Hot).

This fixed S3 exit on both TGL and ADL. Tested on StarBook
Mk V and Mk VI.
