[PATCH 05/12] arm: dts: iot2050: Use the auto generator nodes for fdt

[Jan Kiszka]

From: Su Baocheng <baocheng.su at siemens.com>

Refactor according to the entry `fit: Entry containing a FIT` of
document tools/binman/README.entries.

As the generator uses the device tree name for the config description,
board_fit_config_name_match requires a small adjustment as well.

[Jan: re-add now required CONFIG_OF_LIST, update config matching]
