Subject: [PATCH v4 08/11] mtd: spi-nor: Stop exporting spi_nor_restore()

Some SPI NOR controllers that used this method were moved to
drivers/spi/. We don't accept new support for the existing SPI NOR
controllers drivers under drivers/mtd/spi-nor/controllers/ and we
encourage their owners to move the drivers under drivers/spi/.
Make spi_nor_restore() private as we're going to use it just in core.c.

 initialize the necessary fields for spi_nor{}. Please see
 drivers/mtd/spi-nor/spi-nor.c for detail. Please also refer to spi-fsl-qspi.c
 when you want to write a new driver for a SPI NOR controller.
-Another API is spi_nor_restore(), this is used to restore the status of SPI
-flash chip such as addressing mode. Call it whenever detach the driver from
