qede: populate supported link modes maps on module init

Browse source 
Simplify and lighten qede_set_link_ksettings() by declaring static link
modes maps and populating them on module init. This way we save plenty
of text size at the low expense of __ro_after_init and __initconst data
(the latter will be purged after module init is done).
