phy: qcom-qmp-usb: fix sc8280xp PCS_USB offset

[ Upstream commit 4c6b3af3906d0c59497d3bfb07760f3a082b4150 ]

The PCS_USB register block lives at an offset of 0x1000 from the PCS
region on SC8280XP so add the missing offset to avoid corrupting
unrelated registers on runtime suspend.

Note that the current binding is broken as it does not describe the
PCS_USB region and the PCS register size does not cover PCS_USB and the
regions in between. As Linux currently maps full pages, simply adding
the offset to driver works until the binding has been fixed.
