This patch removes the default boot order for pseries machine. This allows
the machine to handle a NULL boot order in case no -boot option is provided.
Thus it helps SLOF firmware to verify if boot order is specified in command
line or not. If no boot order is provided SLOF tries to boot from the
device set in the nvram.

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.

The commit 58229933 introduced a 1-shift for
some offset in DMA emulation.

Before the previous commit, which converted ioport_register_* to
MemoryRegion, the DMA controller registered 8 ioports with the following
formula:
base + ((8 + i) << d->shift) where 0 <= i < 8
When an IO occured within a Memory Region, DMA callback receives an
offset relative to the start address. Here the start address is:
base + (8 << d->shift).
The offset should be: (i << d->shift). After the shift is reverted, the
offsets are 0..7 not 1..8.

Fixes LP#1089996.
