[media] rc-core: allow calling rc_open with device not initialized
The device initialization completes only after calling
input_register_device(). However, rc_open() can be called while
the device is being registered by the input/evdev core. So, we
can't expect that rc_dev->initialized to be true.
Change the logic to don't require initialized == true at rc_open
and change the type of initialized to be atomic.
this way, we can check for it earlier where it is really needed,
without needing to lock the mutex just for testing it.

On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).
This turns out to be caused by max-width (924) not being a multiple of 16.
We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing

[media] v4l: vsp1: Make rwpf operations independent of video device
The rwpf queue operation doesn't queue a buffer but sets the memory
address for the next run. Rename it to set_memory and pass it a new
structure independent of the video buffer than only contains memory
information.

To make the video device nodes optional we need to decouple the [rw]pf
instances from the video devices. Move video devices out of struct
vsp1_rwpf and instantiate them dynamically in the core driver code.

The rwpf field contains a pointer to the rpf or wpf associated with the
