phy: qcom-qmp-usb: move PCS v6 register to the proper header

The commit 39bbf82d8c2b ("phy: qcom-qmp: pcs-usb: Add v6 register
offsets") incorrectly added plain PCS registers to the PCS_USB header.
Move them to a proper location.

phy: qcom-qmp-combo: fix the prefix for the PCS_USB v6 registers

For all other generations, we have been using just the QPHY prefix for
the PCS registers. Remove the _USB part of the QPHY_USB prefix.

phy: qcom-qmp-combo: Square out 8550 POWER_STATE_CONFIG1

There are two instances of the POWER_STATE_CONFIG1 register: one in
the PCS space and another one in PCS_USB.

The downstream init sequence pokes the latter one while we've been poking
the former one (and misnamed it as the latter one, impostor!). Fix that
up to avoid UB.

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.
