These haven't been used since the driver was upstreamed in 2013.
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/radeon/kv_dpm.c:161:40: warning: ‘cpl_cac_config_reg’ defined but not used [-Wunused-const-variable=]
drivers/gpu/drm/radeon/kv_dpm.c:156:40: warning: ‘mc3_cac_config_reg’ defined but not used [-Wunused-const-variable=]
