Commit Message

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, PCIe3 related QMP PHY also requires addtional clk, which is named
as clkref_en. Hence, add this clk into qmp_pciephy_clk_l so that it can be
easily parsed from devicetree during init.
