The lk smp branch changed the gic to have per cpu interrupt handlers
for every interrupt. This is not needed for interrupts that are not
cpu specific.

This add support for the OpenRISC 1000 architecture, and
as the architecture specification defines an on-chip tick-timer
and interrupt controller, drivers for those are included in
this commit.
Support to utilize the MMU is implemented,
and it can be opted in and out with WITH_KERNEL_VM
