pci-arbiter: Probe devices and map regions

This adapts the arbiter to a bug fixed in libpciaccess. We were relying on
the library to probe devices and map regions but it's the arbiter who should
do it.

* pci-arbiter/pcifs.c:
	* create_fs_tree(): probe the device to find regions and rom
* pci-arbiter/func_files.c:
	* io_region_file(): map region on the first access attempt
