soc/amd/cezanne: Add AMD Renoir SOC support
Add AMD SOC Family 17h Renoir CPUIDs per PPR doc #55922
Renoir is similar to Cezanne with only differences in CCX count.
Cezanne has one Zen3 CCX with 8 cores per CCX compared to
the two Zen2 CCX with 4 cores per CCX. Hence, coreboot side
Cezanne SOC code should be mostly compatible with Renoir and
can be leveraged.
