Qiuxu Zhuo 3ff2422442 EDAC/{skx_common,i10nm}: Fix the loss of saved RRL for HBM pseudo channel 0 
[ Upstream commit eeed3e03f4261e5e381a72ae099ff00ccafbb437 ]

When enabling the retry_rd_err_log (RRL) feature during the loading of the
i10nm_edac driver with the module parameter retry_rd_err_log=2 (Linux RRL
control mode), the default values of the control bits of RRL are saved so
that they can be restored during the unloading of the driver.

In the current code, the RRL of pseudo channel 1 of HBM overwrites pseudo
channel 0 during the loading of the driver, resulting in the loss of saved
RRL for pseudo channel 0. This causes the RRL of pseudo channel 0 of HBM to
be wrongly restored with the values from pseudo channel 1 when unloading
the driver.

Fix this issue by creating two separate groups of RRL control registers
per channel to save default RRL settings of two {sub-,pseudo-}channels.
