auxdisplay: img-ascii-lcd: Use device_get_match_data() 

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

[ As discussed, used `dev` and moved call to `cfg`'s initialization. ]
