Subject: libata: Enable queued TRIM for Samsung SSD 860

From: Ju Hyung Park <qkrwngud825@xxxxxxxxx>

commit ca6bfcb2f6d9deab3924bf901e73622a94900473 upstream.

Samsung explicitly states that queued TRIM is supported for Linux with
860 PRO and 860 EVO.

Make the previous blacklist to cover only 840 and 850 series.
