scsi_da: add 4K quirks for Samsung SSD 860 and 870
Although the actual flash page size is either 8K or 16K for those
devices (according to different sources of various reliability), they
seem to be optimized for the "industry-standard" emulated 4K block size.
To do: consolidate very similar Samsung SSD entries for 830 - 870
models.
