drivers: net: davinci_mdio: use pinctrl PM helpers
This utilize the new pinctrl core PM helpers to transition the driver to "default" and "sleep" states. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
