phy: qcom-qmp-combo: fix NULL-deref on runtime resume
Commit fc64623637da ("phy: qcom-qmp-combo,usb: add support for separate
PCS_USB region") started treating the PCS_USB registers as potentially
separate from the PCS registers but used the wrong base when no PCS_USB
offset has been provided.
Fix the PCS_USB base used at runtime resume to prevent dereferencing a
NULL pointer on platforms that do not provide a PCS_USB offset (e.g.
SC7180).
Fixes: fc64623637da ("phy: qcom-qmp-combo,usb: add support for separate PCS_USB region")
