This patch adds hypervisor console driver for Celleb platform.

Nice small driver. Still, I'd like to know why there is no support
for interrupts to notify the kernel of incoming characters. This seems
to have the same (mis-)design as the IBM blade with the rtas console
that uses no interrupts.

This is caused because the design goal of "console" I/O for Beat is
for debugging Guest OSes that cannot handle interrupts. Adding to that,
the "console" I/O for Beat is deeply inspired by pSeries's one.

Thank you,
