Use PCI standard marco dev_is_pci() instead of directly compare
pci_bus_type to check whether it is pci device.

Yijing,

This one looks good.

While I take a look at the source code, there are around 20 places with
similar style. Do you think it would be good to change all these places
in one patch?

I sent the other similar changes to related maillist, some of them (David, Greg )has been accepted,
and other is not. :)

eg.
http://article.gmane.org/gmane.linux.kernel/1608341/match=dev_is_pci

Thanks!
Yijing.
