Currently, M25P80 uses an object property to differentiate between flash parts.
Changed this over to use QOM sub-classes - the actual names of the different parts
are used to create a set of dynamic classes which passes the part info as class
data. The object no longer needs to search the known_devices table for itself,
instead it just gets its info from its own class.
Kept the intermediate class definition private to m25p80.c for the moment, as
the expectation is parts will only be added as new entries in the table. We can
factor out the TYPE_M25P80 abstraction into a header on a demand basis.

Pulled the qdev_create functionality out of xilinx_axiethernet_create() and
pushed it up to the petalogix_ml605_mmu machine model. This makes the ethernet
create+init process consistent with the AXI DMA. Renamed function to
xilinx_axiethernet_init accordingly.

This patch makes default boot order machine specific instead of
set globally. The default boot order can be set per machine in
QEMUMachine boot_order. This also allows a machine to receive a
NULL boot order when -boot isn't used and take an appropriate action
accordingly. This helps machine boots from the devices as set in
guest's non-volatile memory location in case no boot order is
provided by the user.

Move public headers to include/net, and leave private headers in net/.
Put the virtio headers in include/net/tap.h, removing the multiple copies
that existed. Leave include/net/tap.h as the interface for NICs, and
net/tap_int.h as the interface for OS-specific parts of the tap backend.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"

Split serial.c into serial.c, serial.h and serial-isa.c. While being at
creating a serial.h header file move the serial prototypes from pc.h to
the new serial.h. The latter leads to s/pc.h/serial.h/ in tons of
boards which just want the serial bits from pc.h

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init
functions in the future;
- Let machine initialization forward the init arguments to other
functions more easily.
This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

Re-implemented the interconnect between the Xilinx AXI ethernet and DMA
controllers. A QOM interface "stream" is created, for the two stream interfaces.
As per Edgars request, this is designed to be more generic than AXI-stream,
so in the future we may see more clients of this interface beyond AXI stream.
This is based primarily on Paolos original refactoring of the interconnect.

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.

cfi02 is annoying in that is ignores some address bits; we probably
