phy: qcom-qmp: qserdes-txrx: Add complete QMP PCIe PHY v8 register offsets

Kaanapali SoC uses QMP PHY with version v8 for PCIe Gen3 x2, but requires
a completely unique qserdes-txrx register offsets compared to existing v8
offsets.

Hence, add a dedicated header file containing the FULL SET of qserdes-txrx
register definitions required for Kaanapali's PCIe PHY operation.
