[PATCH v3 11/13] phy: qcom-qmp-usb: rework regs layout arrays

[Dmitry Baryshkov]

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.
