soc/intel/pantherlake: Populate and pass DRAM info for SMBIOS
This patch implements the `save_dimm_info()` API to populate and pass DRAM-related information to the next stage. This information is used to generate the SMBIOS memory table, providing details about installed DIMMs. This addresses the issue where SMBIOS lacked detailed DIMM information. Verified that `dmidecode` correctly dumps the DIMM information from the SMBIOS table after this change. BUG=b:376103463 TEST=Built and booted successfully. Verified DIMM info in SMBIOS using `dmidecode`. > dmidecode -t 17 ``` Getting SMBIOS data from sysfs. SMBIOS 3.0 present.
