phy: qcom: qmp-combo: move driver data initialisation earlier
Commit 44aff8e31080 ("phy: qcom-qmp-combo: clean up probe
initialisation") removed most users of the platform device driver data,
but mistakenly also removed the initialisation despite the data still
being used in the runtime PM callbacks.
The initialisation was soon after restored by commit 83a0bbe39b17 ("phy:
qcom-qmp-combo: add support for updated sc8280xp binding") but now
happens slightly later during probe. This should not cause any trouble
currently as runtime PM needs to be enabled manually through sysfs and
the platform device would not be suspended before the PHY has been
registered anyway.
Move the driver data initialisation to avoid a NULL-pointer dereference
on runtime suspend if runtime PM is ever enabled by default in this
driver.
