media: rcar-vin: Only dynamically allocate v4l2_async_subdev

Browse source 
In preparation of removing the usage of the old helper
v4l2_async_notifier_parse_fwnode_endpoints_by_port() do not dynamically
allocate the whole structure containing the parameters for the parallel
interface, instead only allocate the v4l2_async_subdev structure. There
is no functional change.
