ALSA: hda/ca0132 - make pci_iounmap() call conditional

commit 1e73359a24fad529b0794515b46cbfff99e5fbe6 upstream.

When building without CONFIG_PCI, we can (depending on the architecture)
get a link failure:

ERROR: "pci_iounmap" [sound/pci/hda/snd-hda-codec-ca0132.ko] undefined!

Adding a compile-time check for PCI gets it to work correctly on
32-bit ARM.
