EDAC/amd64: Simplify ECC check on unified memory controllers

commit 74736734 upstream.

The intent of the check is to see whether at least one UMC has ECC
enabled. So do that instead of tracking which ones are enabled in masks
which are too small in size anyway and lead to not loading the driver on
Zen4 machines with UMCs enabled over UMC8.
