EDAC, i10nm: Check ECC enabling status per channel
The i10nm_edac only checks the ECC enabling status for the first
channel of the memory controller. If there aren't memory DIMMs
populated on the first channel, but at least one DIMM populated
on the second channel, it will wrongly report that the ECC for
the memory controller is disabled that fails to load the i10nm_edac
driver. Fix it by checking ECC enabling status per channel.
[Tony: Also report which channel has ECC disabled]
