cpu: introduce CPUClass::virtio_is_big_endian()
If we want to support targets that can change endianness (modern PPC and
ARM for the moment), we need to add a per-CPU class method to be called
from the virtio code. The virtio_ prefix in the name is a hint for people
to avoid misusage (aka. anywhere but from the virtio code).
The default behaviour is to return the compile-time default target
endianness.
