soc/amd: introduce and use get_pstate_core_uvolts for SVI2 and SVI3
Since SVI3 has the CPU voltage ID split into two parts, a serial voltage
ID version specific function is needed to get the raw core VID value.
This will allow making get_pstate_core_power common for all AMD CPUs in
a follow-up patch.
