AER uses a separate trace interface by now. To make it
consistent, move it into unified RAS trace interface.

There's inconsistency between dmesg and the trace event output.
When dmesg says "severity=Corrected", the trace event says
"severity=Fatal". What happens is that HW_EVENT_ERR_CORRECTED is
defined in edac.h:
enum hw_event_mc_err_type {
HW_EVENT_ERR_CORRECTED,
HW_EVENT_ERR_UNCORRECTED,
HW_EVENT_ERR_FATAL,
HW_EVENT_ERR_INFO,
};
while aer_print_error() uses aer_error_severity_string[] defined as:
static const char *aer_error_severity_string[] = {
"Uncorrected (Non-Fatal)",
"Uncorrected (Fatal)",
"Corrected"
};
In this case dmesg is correct because info->severity is assigned in
aer_isr_one_error() using the definitions in include/linux/ras.h:

This header file will define a new trace event that will be triggered when
a AER event occurs. The following data will be provided to the trace
event.
char * dev_name - The name of the slot where the device resides
([domain:]bus:device.function).
u32 status - Either the correctable or uncorrectable register
indicating what error or errors have been see.
u8 severity - error severity 0:NONFATAL 1:FATAL 2:CORRECTED
The trace event will also provide a trace string that may look like:
"0000:05:00.0 PCIe Bus Error:severity=Uncorrected (Non-Fatal), Poisoned
TLP"
