PCI/xilinx: Depend on OF instead of the ARCH

There isn't a hard dependency of the Xilinx AXI-PCIe host bridge on any
architecture.  For example: at SiFive we map RISC-V cores to Xilinx FPGAs
and connect the Xilinx IP via a TileLink adapter, so the RISC-V Linux
port will need to be able to enable PCIE_XILINX in order to have PCIe
support.

This patch decouples the PCIE_XILINX support from ARCH.  Instead it just
depends on OF, which is the only true dependency.

           Say 'Y' here if you want kernel to support the Xilinx AXI PCIe
           Host Bridge driver.
