Since commit 2b3e88ea6528 ("net: phy: improve phy state checking")
phy_start_aneg() expects phy state to be >= PHY_UP. Call phy_start()
before calling phy_start_aneg() during probe so that autonegotiation
is initiated.

As phy_start() takes care of calling phy_start_aneg(), drop the explicit
call to phy_start_aneg().

Network fails without this patch on Octeon TX.

Fixes: 2b3e88ea6528 ("net: phy: improve phy state checking")

v2:
-Add fixes tag and net tree as suggested by Andrew Lunn
v1:
-Remove call to phy_start_aneg() as suggested by Andrew Lunn
-Fix reference to patch in change log as suggested by Sergei Shtylyov
