Subject: [PATCH v3 0/3] PCI/AER, CXL: Fix appropriate _OSC check for CXL RAS Cap

This series of patches fixes the appropriate _OSC check for CXL RAS
registers.

First patch addresses the _OSC check.

Second patch moves around pcie_aer_is_native() function declaration to a
common location to be used by cxl/pci module and third patch reuses
pcie_aer_is_native() in cxl/pci module.

cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS
registers
PCI/AER: Export pcie_aer_is_native()
cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native()
