[media] winbond-cir: use sysfs wakeup filter
Now that we can select the exact variant of the protocol for wakeup filter, the winbond-cir can use the wakeup filter rather than module parameters. Signed-off-by: Sean Young <sean@mess.org> Cc: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
