Xiaofei Tan b194a77fcc efi: cper: print AER info of PCIe fatal error 
AER info of PCIe fatal error is not printed in the current driver.
Because APEI driver will panic directly for fatal error, and can't
run to the place of printing AER info.

An example log is as following:
{763}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 11
{763}[Hardware Error]: event severity: fatal
{763}[Hardware Error]:  Error 0, type: fatal
{763}[Hardware Error]:   section_type: PCIe error
{763}[Hardware Error]:   port_type: 0, PCIe end point
{763}[Hardware Error]:   version: 4.0
{763}[Hardware Error]:   command: 0x0000, status: 0x0010
{763}[Hardware Error]:   device_id: 0000:82:00.0
{763}[Hardware Error]:   slot: 0
{763}[Hardware Error]:   secondary_bus: 0x00
{763}[Hardware Error]:   vendor_id: 0x8086, device_id: 0x10fb
{763}[Hardware Error]:   class_code: 000002
Kernel panic - not syncing: Fatal hardware error!

This issue was imported by the patch, '37448adfc7ce ("aerdrv: Move
cper_print_aer() call out of interrupt context")'. To fix this issue,
this patch adds print of AER info in cper_print_pcie() for fatal error.

Here is the example log after this patch applied:
{24}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 10
{24}[Hardware Error]: event severity: fatal
