drm/amd/pm: Add throttle limit for SMU v13.0.6 

CTF limit represents the max operating temperature and thermal limit
gives the limit at which throttling starts. Add support for both limits.
SOC and HBM may have different limit values.*_emergency_max gives  max
operating temperature and *_crit_max value represents throttle limit.
