PCI/CXL: Export native CXL error reporting control
CXL _OSC Error Reporting Control is used by the OS to determine if
Firmware has control of various CXL error reporting capabilities
including the event logs.
Expose the result of negotiating CXL Error Reporting Control in struct
pci_host_bridge for consumption by the CXL drivers.
