[not upstream as the driver is deleted in 4.16 - gregkh]

The lirc config documented here
https://www.blushingpenguin.com/mark/blog/?p=24 uses raw_codes for sending
IR. Each key only has one pulse, which in fact is an index into the
haup-ir-blaster.bin file. Changing the driver to LIRCCODE (although more
accurate) breaks this configuration.

This code has been replaced completely in kernel v4.16 by a new driver,
see commit acaa34bf06e9 ("media: rc: implement zilog transmitter"), and
commit f95367a7b758 ("media: staging: remove lirc_zilog driver").

This reverts commit 89d8a2cc51d1f29ea24a0b44dde13253141190a0.

Fixes: 615cd3fe6ccc ("[media] media: lirc_dev: make better use of file->private_data")
