copier: Add bind function to configure source/sink buffers params

Setting the source/sink buffers parameters in the copier_update_params
function is not sufficient. If a sink buffer is attached during copier
operation, the module will not set buffers parameters. Move the buffer
parameter configurations to the new copier_bind bind function. Delete
the sink buffers configurations from the copier_module_copy function.
There is no need to configure sink buffers parameters on each copy.
We are assured that they were configured at the time of bind.
