[PATCH 01/17] drivers: support PCIe in RISCV

[Palmer Dabbelt]

From: "Wesley W. Terpstra" <wesley@xxxxxxxxxx>

There are RISC-V systems that have been mapped to Xilinx FPGAs that have
their PCIe controllers on chip.  These build system changes allow RISC-V
systems to enable the Xilinx PCIe controller, and to setup PCIe IRQs.
