[media] rc: nuvoton-cir: Add support for writing wakeup samples via sysfs filter callback

Browse source 
Nuvoton-cir utilizes the encoding capabilities of rc-core to convert
scancodes from user space to pulse/space format understood by the
underlying hardware.

Converted samples are then written to the wakeup fifo along with other
necessary configuration to enable wake up functionality.
