net: ethernet: fs_enet: Cleanup and phylink conversion

This is V3 of a series that cleans-up fs_enet, with the ultimate goal of
converting it to phylink (patch 8).

The main changes compared to V2 are :
 - Reviewed-by tags from Andrew were gathered
 - Patch 5 now includes the removal of now unused includes, thanks
   Andrew for spotting this
 - Patch 4 is new, it reworks the adjust_link to move the spinlock
   acquisition to a more suitable location. Although this dissapears in
   the actual phylink port, it makes the phylink conversion clearer on
   that point
 - Patch 8 includes fixes in the tx_timeout cancellation, to prevent
   taking rtnl twice when canceling a pending tx_timeout. Thanks Jakub
   for spotting this.
