[PATCH] riscv: Repeat virtio scan

[Łukasz Stelmach]

The first time virtio_init() gets called from board_init() PCI isn't
ready. Thus any virtio-over-PCI (e.g. network interfaces) devices can't
be detected and used without additional `virtio scan` scan in the shell
or a script.

The patch works for my but:

a) maybe virtio_init() should called only from board_init() the same
   way as on ARM?

b) can a repeated virtio_init() break already detected/initialized
   devices?
