soc/intel/alderlake: Fix unknown voltage in SMBIOS 

The current SMBIOS for coreboot is missing processor info for Alder Lake and Raptor Lake SoC, specifically, voltage, max speed,
and upgrade (socket type). This patch implements voltage function.
Refer to SMBIOS spec sheet for documentation:
https://web.archive.org/web/20221012222420/https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.6.0.pdf

BUG=NONE
BRANCH=firmware-brya-14505.B
TEST=Boot and verified that SMBIOS processor voltage value is correct.
