Subject: [PATCH v3 1/2] mtd: rawnand: pl353: Fix software ECC support

From: Andrea Scian <andrea.scian@...e.eu>

We need to set also write_page_raw in ecc structure to allow
choosing SW ECC instead of HW one, otherwise write operation fail.

Fixes: 08d8c62164a322 ("mtd: rawnand: pl353: Add support for the ARM PL353 SMC NAND controller")
