The variable cfi_flash_num_flash_banks is defined iff CONFIG_SYS_MAX_FLASH_BANKS_DETECT is defined, but it is used unconditionally in the function cfi_flash_init_dm. This leads to a undefined variable compile error when CONFIG_SYS_MAX_FLASH_BANKS_DETECT is not defined, but DM is enabled.
Fix this by always defining the cfi_flash_num_flash_banks variable.
