v4l2-int-if: Export more interfaces to modules

From: Sakari Ailus <sakari.ailus@nokia.com>

Export v4l2_int_device_try_attach_all. This allows initiating the
initialisation of int if device after the drivers have been registered.

Also allow drivers to call ioctls if v4l2-int-if was compiled as
module.

Priority: normal
