Currently driver supports only x4 lane based functionality using tx/rx and
tx2/rx2 pair of register sets. To support 8 lane functionality with PCIe3,
PCIe3 related QMP PHY provides additional programming which are available
as txz and rxz based register set. Hence adds txz and rxz based registers
usage and programming sequences. Phy register setting for txz and rxz will
be applied to all 8 lanes. Some lanes may have different settings on
several registers than txz/rxz, these registers should be programmed after
txz/rxz programming sequences completing.

Besides, x1e80100 SoC uses QMP phy with version v6.30 for PCIe Gen4 x8.
Add the new register offsets in a dedicated header file.
