fix cyclades compile with !PCI

I got the following compile error in 2.6.6-mm1 (but not specific to -mm) with CONFIG_PCI=n:

<-- snip -->

...
CC drivers/char/cyclades.o
drivers/char/cyclades.c: In function `cy_cleanup_module':
drivers/char/cyclades.c:5638: warning: implicit declaration of function `pci_release_regions'
...
LD .tmp_vmlinux1
make: *** [.tmp_vmlinux1] Error 1

<-- snip -->

The patch below fixes this issue.

Please apply
