Subject: [PATCH] mtd_dataflash: fix probing of AT45DB321C chips.

Commit c7e9f849de39bb8a1a9ee7665a28fae1f4f2d5a4 ("[MTD] DataFlash: bugfix,
binary page sizes now handled") broke support for probing AT45DB321C flash
chips.  These chips do not support the "page size" status bit, so if we
match the JEDEC id return early.
