Philippe Bergheaud 87db7579eb ocxl: control via sysfs whether the FPGA is reloaded on a link reset
Some opencapi FPGA images allow to control if the FPGA should be reloaded
on the next adapter reset. If it is supported, the image specifies it
through a Vendor Specific DVSEC in the config space of function 0.
