Wu Hao 6e8fd6e493 fpga: dfl: add dfl_fpga_port_ops support. ... In some cases, other DFL driver modules may need to access some port operations, e.g. disable / enable port for partial reconfiguration in FME module. In order to avoid dependency between port and FME modules, this patch introduces the dfl_fpga_port_ops support in DFL framework. A global dfl_fpga_port_ops list is added in the DFL framework, and it allows other DFL modules to use these port operations registered to this list, even in virtualization case, the port platform device is turned into VF / guest VM and hidden in host, the registered port_ops is still usable. It resolves the dependency issues between modules, but once get port ops API returns a valid port ops, that means related port driver module has been module_get to prevent from unexpected unload, and put port ops API must be invoked after use. These APIs introduced by this patch is listed below: * dfl_fpga_port_ops_add add one port ops to the global list. * dfl_fpga_port_ops_del del one port ops from the global list. * dfl_fpga_port_ops_get / dfl_fpga_port_ops_put get/put the port ops before/after use.
