Subject: [PATCH v2 4/8] phy: qcom-qmp: pcs-usb: Add v6 register offsets

The new SM8550 SoC bumps up the HW version of QMP phy to v6 for USB.
Add the new PCS USB specific offsets in a dedicated header file.

The v1 version of this patch was here:
https://lore.kernel.org/all/20221116120157.2706810-2-abel.vesa@linaro.org/

Changes since v1:
 * split all the offsets into separate patches, like Vinod suggested
