Staging: sep: SEP driver build breaks with CONFIG_PCI=n

next-20090813 randconfig build breaks Discretix SEP driver when
configured with CONFIG_PCI=n.

drivers/staging/sep/sep_driver.c: In function 'sep_probe':
drivers/staging/sep/sep_driver.c:2548: error: implicit declaration of function 'pci_dev_get'

This patch adds the dependency on PCI for the DX SEP driver.
