stmmac: don't go through ethtool to start auto-negotiation 

The driver used to call phy's ethtool configuration routine to start
auto-negotiation. This change has it call directly phy's routine to
start auto-negotiation.

The initial version was hiding phy_start_aneg() return value,
this patch returns it (<0 upon error).

Tested: module compiles, tested on STM HDK7108 STB.
