phy: qcom-qmp-usb: rework regs layout arrays

Use symbolic names for the values inside reg layout arrays. New register
names are added following the PCS register layout that is used by the
particular PHY.

Note: ipq8074 tables appear to use a mixture of v2 and v3 registers.
This might need additional fixes.
