Qiuxu Zhuo 4742ae4d82 EDAC/{skx_common,i10nm}: Prepare RRL for sub-channel granularity 
To prepare for enabling Diamond Rapids server RRL (Retry Read error Log),
which operates at sub-channel granularity by converting struct
res_config::reg_rrl_ddr from a single pointer to an array (reg_rrl_ddr[2])
and updating all users in i10nm_edac and skx_common accordingly.

Initialize only reg_rrl_ddr[0] for existing platforms and prepare for
supporting two RRL set groups per DDR channel (one per sub-channel)
when present.
