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
