Subject: [PATCH v2 3/5] ACPI/PCI: Add AER bits #defines for PCIe to PCI/PCI-X Bridge

From: leoliu-oc <leoliu-oc@...oxin.com>

Define secondary uncorrectable error mask register, secondary
uncorrectable error severity register and secondary error capabilities and
control register bits in AER capability for PCIe to PCI/PCI-X Bridge.
Please refer to PCIe to PCI/PCI-X Bridge Specification, sec 5.2.3.2,
5.2.3.3 and 5.2.3.4.
