[PATCH v4] RISC-V: defconfig: Enable Generic PCIE by default

[Alistair Francis]

Enable generic PCIe by default in the RISC-V defconfig, this allows us
to use QEMU's PCIe support out of the box.

Looks good:

Alistair, is there a ready-made qemu machine with riscv + pcie?
That would be really useful for testing..

Yep, if you use master QEMU (it isn't in a release yet) the virt
machine has PCIe support.

Cool.  Time to play around with the latest qemu tree..
