[PATCH v10 10/12] tools/libxl: move PCI-related macros in a header file

[Arianna Avanzini <avanzini.arianna@gmail.com>]

Currently, the PCI-related macro used by libxl are in the libxl_pci.c
source file. This commit moves them to a new libxl_pci.h header; such a
change is instrumental to the following commit, as it lets other libxl
source files be able to access the macros by including the header.
