fcef6924b8 Allow BERI virtio-platform code to operate with no PIO devices specified.
We will use it with Bluespec simulator of CHERI processor for invalidating
caches only.

436ac49059 Do not configure Altera PIO device on ARM startup.
PIO is a device implemented in soft-core and becomes
available after flashing FPGA only.
