Thomas Richard dd8b9ba3d9 phy: freescale: imx8qm-hsio: fix NULL pointer dereference 
[ Upstream commit 4dd5d4c036 ]

During the probe the refclk_pad pointer is set to NULL if the
'fsl,refclk-pad-mode' property is not defined in the devicetree node. But
in imx_hsio_configure_clk_pad() this pointer is unconditionally used which
could result in a NULL pointer dereference. So check the pointer before to
use it.
