PCI/AER: Support errors introduced by PCIe r6.0

commit 6633875250b38b18b8638cf01e695de031c71f02 upstream.

PCIe r6.0 defined five additional errors in the Uncorrectable Error
Status, Mask and Severity Registers (PCIe r7.0 sec 7.8.4.2ff).

lspci has been supporting them since commit 144b0911cc0b ("ls-ecaps:
extend decode support for more fields for AER CE and UE status"):

  https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git/commit/?id=144b0911cc0b

Amend the AER driver to recognize them as well, instead of logging them as
"Unknown Error Bit".
