[PATCH v3 02/25] mtd: spi-nor: core: Use container_of to get the pointer to struct spi_nor

[Tudor Ambarus <tudor.ambarus@microchip.com>]

"struct mtd_info mtd" is member of "struct spi_nor", there's no need
to use "mtd->priv". Get the pointer to the containing struct spi_nor
by using container_of. While here, make the function inline and
get rid of the __maybe_unused.
