uio: dfl: add vendor-specific feature id
Add a Device Feature List (DFL) feature id as a generic mechanism to expose a vendor-specific FPGA IP to user space. The feature id is intended for use with IPs that do not need any kernel services beyond exposure to user space through the UIO DFL driver. The feature id is used in, e.g., Intel Oak Springs Canyon IPUs to expose various IPs to user space, e.g., Network Controller Sideband Interface (NC-SI), BaseNIC, and VirtIO management.
