[media] nuvoton-cir: fix wake from suspend
The CIR Wake FIFO is 67 bytes long, but the stock remote appears to only
populate 65 of them. Limit comparison to 65 bytes, and wake from suspend
works a whole lot better (it wasn't working at all for most folks).
Fix based on comparison with the old lirc_wb677 driver from Nuvoton,
debugging and testing done by Dave Treacy by way of the lirc mailing
list.
