virtIO console driver improvements #265

The virtIO console driver is pretty simple and definitely not written with performance in mind.

Below are a couple of possible improvements if we revisited the driver:

make it use a serial design oriented around DMA instead of byte-by-byte transfer. The device transfers data via DMA and our current serial design is intended only for byte-by-byte devices.
have one 'virtio region' that is used for all virtqs, rx data, tx data.
revisit descriptor handling, right now we have descriptors of length 1.
