phy: qcom-qmp-combo: fix runtime suspend

commit c7b98de745cffdceefc077ad5cf9cda032ef8959 upstream.

Drop the confused runtime-suspend type check which effectively broke
runtime PM if the DP child node happens to be parsed before the USB
child node during probe (e.g. due to order of child nodes in the
devicetree).

Instead use the new driver data USB PHY pointer to access the USB
configuration and resources.
