phy: freescale: imx8qm-hsio: fix NULL pointer dereference
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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
