[PATCH v3] drm/bridge: Remove extra device acquisition method of i2c client in lt9611 driver

drm/bridge: Remove extra device acquisition method of i2c client in lt9611 driver.

We have got the device of i2c client in probe function.So we should remove extra
device acquisition method of i2c client.

The commit title is already in the email title, it doesn't need to be
sent twice, sorry if I was unclear about this.

This line is too long, and `checkpatch.pl --strict` complains about its length.

would suggest running `checkpatch.pl --strict` on every patch before
emailing them out. It's very easy to miss something.
