To support this, add a common structure for forced speed maps and a function to init them. This is solution was originally introduced in commit 1d4e4ecccb11 ("qede: populate supported link modes maps on module init") for qede driver. ethtool_forced_speed_maps_init() should be called during driver init with an array of struct ethtool_forced_speed_map to populate the mapping. Definitions for maps themselves are left in the driver code, as the sets of supported link modes may vary between the devices. The qede driver was compile tested only.
