[PATCH RESEND 5/5] mtd: nand: Remove unused chip->write_page() hook

[Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>]

The last/only user of the chip->write_page() hook (the Atmel NAND
controller driver) has been reworked and is no longer specifying a custom
->write_page() implementation.
Drop this hook before someone else start abusing it.
