[PATCH v4 08/20] EDAC/synopsys: Drop internal CE and UE counters

First of all these counters aren't exposed anyhow from the driver.
Secondly the EDAC core already tracks the total amount of the correctable
and uncorrectable errors (see mem_ctl_info.{ce_mc,ue_mc} fields usage).
Drop the useless internal counters then for good.

Changelog v4:
- Drop redundant empty line.
- Drop private counters access from the check_errors() method too.
