soc/amd/common/cpu/tsc: factor out family-specific get_pstate_core_freq
Factor out the get_pstate_core_freq function from the SoC's acpi.c files
to both avoid duplication and to also be able to use the same function
in the TSC frequency calculation in a follow-up patch. The family 17h
and 19h SoCs use the same frequency encoding in the P state MSRs while
the family 1Ah SoCs use a different encoding. The family 15h and 16h
SoCs use another encoding, but since this isn't implemented in
Stoneyridge's acpi.c, this will be added in a follow-up patch.
