vga_switcheroo: Introduce struct vga_switcheroo_client_ops
This changes the API as a clean-up. Instead of passing multiple
function pointers at each time, introduce a new struct holding the
whole callback functions and pass it to the registration.
The same struct will be used for the upcoming audio client
registration, too.
