In the case of injecting uncorrected error with background workload,
the deferred error among uncorrected errors need to be specified
by checking the deferred and poison bits of status register.
v2: refine checking for deferred error
v2: log possiable DEs among CEs
v2: generate CPER records for DEs among UEs

ACA error types managed by driver a direct 1:1
correspondence with those managed by firmware.
To address this, for each ACA bank, include
both the ACA error type and the ACA SMU type.
This addition is useful for creating CPER records.
