From: Shiju Jose <shiju.jose@huawei.com>

Add handling of following new fields in trace aer_event
for advisory non-fatal and other errors.

  - cor_status		(Correctable Error Status)
  - cor_mask		(Correctable Error Mask)
  - uncor_status	(Uncorrectable Error Status)
  - uncor_severity	(Uncorrectable Error Severity)
  - uncor_mask		(Uncorrectable Error Mask)
  - aer_cap_ctrl	(AER Capabilities and Control)
  - link_status		(Link Status)
  - device_status	(Device Status)
  - device_control_2	(Device Control 2)

https://lore.kernel.org/lkml/20240125062802.50819-5-qingshun.wang@linux.intel.com/

Question: Does "aer_event" table in SQLite DB  to be rename,
for example "aer_event_v2" because new fields are added?
