[PATCH 1/1] dfu: add missing dependency for SPI flash DFU driver

[Heinrich Schuchardt]

Building the SPI flash DFU driver fails if SPI flash support is missing.

    drivers/dfu/dfu_sf.c:123:29: error:
    ‘CONFIG_SF_DEFAULT_MODE’ undeclared (first use in this function);

Add the missing dependency.
