If 'IS_ERR(pdata->clk)' is true, then 'clk_disable_unprepare(pdata->clk)'
will do nothing.
It is likely that 'if (!IS_ERR(pdata->clk))' was expected here.
In fact, the test can even be removed because 'clk_disable_unprepare'
already handles such cases.

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

Currently, SGMII based 1G rely on the hardware registers for link state
and sometimes it's not reliable. To get most accurate link state, this
interface has to use the MDIO bus to poll the PHY.
In X-Gene SoC, MDIO bus is shared across RGMII and SGMII based 1G
interfaces, so adding this driver to manage MDIO bus. This driver
registers the mdio bus and registers the PHYs connected to it.
