phy: rockchip: Support PCIe v3
RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.
Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.
Add data-lanes property for splitting pcie-lanes across controllers.
The data-lanes is an array where x=0 means lane is disabled and x > 0
means controller x is assigned to phy lane.
