[PATCH] rapidio: fix missing include of <linux/rio_drv.h>

["Ben Dooks (Codethink)" <ben.dooks@codethink.co.uk>]

Include <linux/rio_drv.h> for the missing declarations
of functions exported from this file. Fixes the following
sparse warnings:

drivers/rapidio/rio-driver.c:53:16: warning: symbol 'rio_dev_get' was not declared. Should it be static?
drivers/rapidio/rio-driver.c:70:6: warning: symbol 'rio_dev_put' was not declared. Should it be static?
drivers/rapidio/rio-driver.c:150:5: warning: symbol 'rio_register_driver' was not declared. Should it be static?
drivers/rapidio/rio-driver.c:169:6: warning: symbol 'rio_unregister_driver' was not declared. Should it be static?
