media: Remove the legacy v4l2-clk API
The V4L2 temporary clock helper API, was introduced in late 2012 and, as mentioned in the documentation, meant to be replaced by the generic clock API, once the generic clock framework became available on all relevant architectures. The generic clock API is a well-established API (since a few years now). The last few media capture drivers and sensors using v4l2-clk have been converted to the generic clock framework. We can now remove the v4l2-clk API.
