soc/amd/common/cpu/Kconfig: use Cxxx as CPU string for all non-CAR SoCs
Picasso already uses the Cxxx ACPI CPU device naming scheme, due to it
being what the AGESA reference code uses. We initially relied on the
AGESA/FSP generated SSDT for the P- and C-state support before we had a
native implementation for this in coreboot. The Cxxx naming scheme can
also be used for the other AMD SoCs except Stoneyridge which is pre-Zen
and doesn't select SOC_AMD_COMMON_BLOCK_NONCAR. The main advantage of
using Cxxx instead of CPxx is that the Cxxx scheme supports systems with
more than 256 CPU threads.
