QEMU fails when used with the following command line:
./ppc64-softmmu/qemu-system-ppc64 -S -machine 40p -device i82374
qemu-system-ppc64: hw/isa/isa-bus.c:110: isa_bus_dma: Assertion `!bus->dma[0] && !bus->dma[1]' failed.
The 40p machine type already creates the device i82374. If specified in the
command line, it will try to create it again, hence generating the error. The
function isa_bus_dma() isn't supposed to be called twice for the same bus.
Check the bus doesn't already have a DMA controller registered before creating
the device.

- Move the header from hw/isa/ to hw/dma/
- Remove the old i386/pc dependency
- use a bool type for the high_page_enable argument

This is unused. cpu_exit now is almost exclusively an internal function
to the CPU execution loop. In a few patches, we'll change the remaining
occurrences to qemu_cpu_kick, making it truly internal.

PortioList is an abstraction used for construction of MemoryRegionPortioList
from MemoryRegionPortio. It can be used later to unmap created memory regions.
It also requires proper cleanup because some of the memory inside is allocated
dynamically.
By moving PortioList ot device state we make it possible to cleanup later and
avoid leaking memory.
This change spans several target platforms. The following testcases cover all
changed lines:
qemu-system-ppc -M prep
qemu-system-i386 -vga qxl
qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0
