EDAC/mc_sysfs: Increase legacy channel support to 12
Newer AMD systems, such as Genoa, can support up to 12 channels per EDAC "mc" device. These are detected by the device's EDAC module, and the current EDAC interface is properly enumerated. However, the legacy EDAC sysfs interface provides device attributes only for channels 0 to 7. Therefore, channels 8 to 11 will not be visible in the legacy interface. This was overlooked in the initial support for AMD Genoa. Add additional device attributes so that up to 12 channels are visible in the legacy EDAC sysfs interface.
