[media] rc: add wakeup_protocols sysfs file
Add a wakeup_protocols sysfs file which controls the new rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of protocols that are used for the wakeup filter. A new RC driver callback change_wakeup_protocol() is called to change the wakeup protocol mask.

+Description:
+ Reading this file returns a list of available protocols to use
+ for the wakeup filter, something like:
+ "rc5 rc6 nec jvc [sony]"
+ The enabled wakeup protocol is shown in [] brackets.
+ Writing "+proto" will add a protocol to the list of enabled
+ wakeup protocols.
+ Writing "-proto" will remove a protocol from the list of enabled
+ wakeup protocols.
+ Writing "proto" will use "proto" for wakeup events.
+ Writing "none" will disable wakeup.
+ Write fails with EINVAL if an invalid protocol combination or
+ unknown protocol name is used, or if wakeup is not supported by
+ the hardware.
