net/phy: enable get_phy_id redefinable
As some PHYs have non-standard PHY ID registers, PHY Id can't be read correctly by current get_phy_id function, so we enable get_phy_id redefinable to permit specific PHY driver having own specific get_phy_id function. Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com>
