[media] rc-main: allow raw protocol drivers to restrict the allowed protos
On some hardware (au0828/au8522), the hardware is broken with
regards to the initial pulse detection. So, the driver needs to
produce a fake start pulse. That limits the acceptable protocols,
as it is not possible to produce a fake pulse that would cover
all supported protocols.
So, allow the driver to explicitly set the allowed protocols.
If the driver doesn't specify, keep the old behavior.
