[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. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
