After a warm reboot, the PHY is left in power-down state
(BMCR_PDOWN set) causing auto-negotiation to timeout when
running the dhcp command.
Fix this by calling phy_reset() in dp83867_config() which
brings the PHY to a known clean state. The existing
DP83867_SW_RESTART is removed as it is redundant after phy_reset().
