Enable generic PCIe by default in the RISC-V defconfig, this allows us

Odd -- when your QEMU patches came through I tried doing this, which resulted in a non-booting kernel. For some reason this patch is fine, though. I'm going to just assume I screwed this up the first time, so it looks like this and the QEMU patch are good to go.

Thanks!
