qed, qede: add support for new operating modes

This series covers the support for the following:
 - new port modes;
 - loopback modes, previously missing;
 - new speed/link modes;
 - several FEC modes;
 - multi-rate transceivers;

and also cleans up and optimizes several related parts of code.

v3 (from [2]):
 - dropped custom link mode declaration; qed, qede and qedf switched to
   Ethtool link modes and definitions (#0001, #0002, per Andrew Lunn's
   suggestion);
 - exchange more .text size to .initconst and .ro_after_init in qede
   (#0003).

v2 (from [1]):
 - added a patch (#0010) that drops discussed dead struct member;
 - addressed checkpatch complaints on #0014 (former #0013);
 - rebased on top of latest net-next;
 - no other changes.
