tools: Fix CPU listing in "cell list"

This fixes the output of patterns like "0,3", i.e. individual CPUs with
a gap in between them.

driver: Use hypervisor's version.h

Let the driver module depend on the hypervisor subdir. This allows us to
reuse the version.h generated by the hypervisor build also for the
driver. They were identical.

core: config.h is expected in the $(obj), not $(src)

Cosmetic change, both are identical in practice (no out-of-tree build
possible for out-of-tree modules right now).

core: Move cpu_suspended setting into arch_panic_stop

cpu_suspended is an x86-specific control, nothing every arch needs to
provide. Leave it up to the arch how to set the CPU's state on panic.

core: Refactor struct mmio_access to mmio_instruction

The current mmio_access rather contains information about the accessing
instruction. ARM's mmio_access hold data about the actual access. To
clarify the meaning and release the namespace, rework the preexisting
struct to mmio_instruction.

core: Move mmio_parse and struct mmio_instruction into arch header

There will be no need for and implementation of this service outside of
x86 in the foreseeable future. So make it arch-private until we have
more users.
