Currently, the v4l2_subdev_state_xlate_streams() function is used
to translate streams from one pad to another.
This function takes the entire subdev state as argument, but only makes
use of the routing.

Introduce a v4l2_subdev_routing_xlate_streams() function which can be
used without the entire subdev state, to avoid passing the entire state
around when not needed.

Convert all usages of v4l2_subdev_state_xlate_streams() to
v4l2_subdev_routing_xlate_streams().

Remove v4l2_subdev_state_xlate_streams().

V2:
* Fix description of parameters

Cosmin Tanislav (3):
media: v4l: subdev: add v4l2_subdev_routing_xlate_streams()
media: use v4l2_subdev_routing_xlate_streams()
media: v4l: subdev: remove v4l2_subdev_state_xlate_streams()
