Subject: mtd: nand: tango: Fix incorrect use of SEQIN command

From: Boris Brezillon <boris.brezillon@free-electrons.com>

commit a186493237a9d8559997c2f97c33c4716d602fd2 upstream.

SEQIN is supposed to be used when one wants to start programming a page.
What we want here is just to change the column within the page, which is
done with the RNDIN command.
