Enabling boot from HYP mode requires the use of some more
virt-specific instructions ("eret" and "msr elr_hyp, reg").

Add the necessary encoding to asm/opcode-virt.h.

For now, this patch just adds a definition for the HVC instruction.
More can be added here later, as needed.

Now that we have a real example of how to use the opcode injection
macros properly, this patch also adds a cross-reference from the
explanation in opcodes.h (since without an example, figuring out
how to use the macros is not that easy).

I have no idea if the beat hypervisor supports multiple cpus in
a partition, but the code has not been touched since these stubs
were added in February of 2007 except to move them in April of 2008.
These are stubs: start_cpu always returns fail (which is dropped),
the message passing and reciving are empty functions, and the top
of file comment says "Incomplete".

This patch includes support for pci buses, base of Celleb specific
devices, and etc. It works on of_platform bus.
