uio: Constify struct pci_device_id

'struct pci_device_id' is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increases overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   4073	   1336	      0	   5409	   1521	drivers/uio/uio_cif.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   4233	   1176	      0	   5409	   1521	drivers/uio/uio_cif.o
