The default behavior of DPDK is to wait the creation of /dev/uioX
devices. This work is usually done by hotplug thanks to the
kernel notification.
On some embedded systems, there is no hotplug program. These 2
patches introduce a new EAL option "--create-uio-dev" that tells
the DPDK to create the /dev/uioX devices using mknod().

To: dev
Add a new function pci_get_uio_dev() that parses /sys/bus/pci/devices
to get the uio device associated with a PCI device. This patch just
moves some code that was in pci_uio_map_resource() in the new function
without any functional change.
Thanks to this change, the next commit will be easier to understand.
Moreover it improves readability: having smaller functions help to
understand what pci_uio_map_resource() does.

When the user specifies --create-uio-dev in dpdk eal start options, the
DPDK will create the /dev/uioX instead of waiting that a program does it
(which is usually hotplug).
This option is useful in embedded environments where there is no hotplug
to do the work.

The option is added in section "EAL options for DEBUG use only".
Shouldn't be in the general section "EAL options" ?
