[PATCH 1/2] net/stmmac: don't go through ethtool to start autonegociation

[David Decotigny]

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

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

Tested: module compiles, NOT tested on real hardware.
