spi-nor/core.c needs to include linux/delay.h,
or it would raise below compile warning:

Drivers/mtd/spi-nor/core.c: In function ‘spi_nor_soft_reset’:
drivers/mtd/spi-nor/core.c:2779:2: error: implicit declaration of function ‘usleep_range’ [-Werror=implicit-function-declaration]
 2779 |  usleep_range(SPI_NOR_SRST_SLEEP_MIN, SPI_NOR_SRST_SLEEP_MAX);
      |  ^~~~~~~~~~~~
