From: Hans Zhang <hans.zhang@xxxxxxxxxxx>
Add pcie_x*_rc node to support Sky1 PCIe driver based on the
Cadence PCIe core.
Supports Gen1/Gen2/Gen3/Gen4, 1/2/4/8 lane, MSI/MSI-x interrupts
using the ARM GICv3.
Signed-off-by: Hans Zhang <hans.zhang@xxxxxxxxxxx>

Changes for v8:
- The rcsu register is split into two parts: rcsu_strap and rcsu_status.
