Subject: [PATCH 05/13] media/pci: convert drivers to use the new vb2_queue dev
field
Stop using alloc_ctx and just fill in the device pointer.

After rebasing the vb2: replace allocation context by device pointer patch series I discovered
that newly committed changes to tw686x required that driver to be updated as well.
This is the patch for that.
