[PATCH] watchdog: orion: Use of_device_get_match_data()

[Rosen Penev <rosenp@gmail.com>]

Use of_device_get_match_data() to fetch watchdog match data directly
instead of open-coding an of_match_device() lookup.

Keep the existing legacy fallback when no match data is available.

This also lets the driver drop the of_device.h include.
