[ Upstream commit bcd752c706c357229185a330ab450b86236d9031 ]

A 14-inch 2560x1600 60Hz matte touch panel, found on a Dell Latitude 7455
laptop (second-source with BOE NE14QDM), according to online sources it's
also found on the Latitude 7440 and some ASUS models.

Don't have datasheet access, but the same timing as for other panels from
the same manufacturer works fine.
