pci: don't overwrite multi functio bit in pci header type.

Don't overwrite pci header type.
Otherwise, multi function bit which pci_init_header_type() sets
appropriately is lost.
Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero
which is already zero cleared.

how to test:
run qemu and issue info pci to see whether a device in question is
normal device, not pci-to-pci bridge.
This is handy because guest os isn't required.

cmd646: pass pci_dev as it needs it

Instead of doing tricks to get the pci_dev, just pass it in the 1st
place. Patch is a bit longer that reverting the pci_dev field, but it
states more clearly (IMHO) what we are doing.

It also fixes the bm test, now that you told me that ->unit is not
always valid.

workaround for cmd646 bmdma register access while no dma is active

This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback
as opaque pointer. This breaks when write to dma
control register of second channel happens when no
dma operation is in progress, so bm->unit is zero
for second channel, and pci_from_bm() returns garbage
pointer. Crash happens shortly after that while
dereferencing that pointer.

v0->v1: cleaned up dead code from pci_from_bm.

qdev: Replace device names containing whitespace

Device names with whitespace require quoting in the shell and in the
monitor. Some of the offenders are also overly long. Some have a
more convenient alias, some don't.

The place for verbose device names is DeviceInfo member desc. The
name should be short & sweet.
