soc/intel/alderlake: Fix unknown upgrade 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 upgrade function.
Refer to SMBIOS spec sheet for documentation on cpu socket values:
https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.6.0.p...

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