[PATCH 001/001] UIO: allow binding uio_dmem_genirq to devices using command line options

[Alfasys]

Add an option to bind the uio_dmem_genirq driver to a given device
using command line options.
Make uio_dmem_genirq match uio_pdrv_genirq functionality added in
commit 05c3e0bb5629 ("UIO: allow binding uio_pdrv_genirq.c to devices 

using command line option")
