[PATCH 04/13] mtd: spi-nor: Rename nor->params to nor->flash

[<Tudor.Ambarus@xxxxxxxxxxxxx>]

From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

Rename nor->params to nor->flash for a clearer separation
between the controller and flash operations.

Signed-off-by: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>
