2024-10-30soc/intel/pantherlake: Set SMBUS device ACPI min sleep state as D0Subrata Banik
This change sets the SMBUS device to min sleep state D0 in the ACPI sleep state table. TEST=Able to build and boot google/fatcat. w/o this patch: [WARN ] Unknown min d_state for PCI: 00:1f.4 w/ this patch: No Error or Warning.

2024-09-27soc/intel/pantherlake: Comply with the no typedef coding style ruleJeremy Compostella
As https://doc.coreboot.org/contributing/coding_style.html#typedefs states: "In general, a pointer, or a struct that has elements that can reasonably be directly accessed should never be a typedef". This commit makes the Intel Panther Lake SoC code comply with this by using explicitly `struct soc_intel_pantherlake_config' in the soc/intel/pantherlake code as I have been suggested to for the `fsp_params.c' files. The rule being the rule and consistency across a project matters more than personal preferences. The documentation lists five exceptions and none on them cover the use of `config_t' instead `struct soc_intel_pantherlake' but I believe it does not make the code better for the following three reasons: 1. It is repetitive, make the line longer and the code is in soc/intel/pantherlake so obviously the config_t data structure is the pantherlake soc configuration. 2. It makes re-usability from one generation to another unnecessarily harder. 3. This config_t abstraction is required for and used by some common block code anyway. Hence, we end-up with some code using `config_t' and other using the final structure which break the consistency of the code when the project in looked as a whole.
