Dave Jiang 53c49b6e6d PCI/CXL: Add 'cxl_bus' reset method for devices below CXL Ports ... By default Secondary Bus Reset (SBR) is masked for CXL Ports (see CXL r3.1, sec 8.1.5.2). Add cxl_reset_bus_function() (method "cxl_bus") to set the "Unmask SBR" bit in the upstream CXL Port before performing the bus reset and restore the original value afterwards. This method allows the user to perform a bus reset on a CXL device without needing to set the "Unmask SBR" bit via a user tool.
