mtd: spi-nor: Stop exporting spi_nor_restore()

Browse Source 
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.

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
device or reboot the system.
