[PATCH v3 15/41] mtd: spi-nor: add SNOR_ID() and SNOR_OTP()

[Michael Walle]

After all the preparation, it is now time to introduce the new macros to
specify flashes in our database: SNOR_ID() and SNOR_OTP(). An flash_info
entry might now look like:
    {
        .id = SNOR_ID(0xef, 0x60, 0x16),
        .otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
        .flags = SPI_NOR_HAS_LOCK | SPI_NOR_HAS_TB,
    }
