Hello,

this is the third version of changes for the Topaz/Peridot family of
switches. The patches apply on net-next.
Changes since v2:
 - per Vivien's request I merged the three different patches operating
   on code for hidden registers into one patch (second in this series)
 - also per Vivien's request I changed the serdes_get_lane method: its
   return value is now used only if error's occur, as the rest of this
   drivers functions do. Lane number is put into a place pointed to
   by the s8 *lane argument. The error semantics also changed: if there
   is no lane on a port, the function should still return 0 and should
   put -1 into *lane. Negative error value should be returned only if
   a real error occurs, for example when a MDIO read operation failed.
 - also per Vivien's request the mv88e6xxx_serdes_get_lane function was
   put into serdes.h as static inline, since it is just a wrapper
 - the patch that simplified SERDES code for Topaz and Peridot families
   was merged into one patch
