🌈 DESCRIPTION 🌈

so what does she actually do? not me explaining this like it's gossip but — dfl_fpga_dev_feature_init takes the sub features and matches them up against the given feature_drvs list, then uses the matched drv to init the related sub feature. it's giving matchmaker energy fr fr 💖 every sub feature that finds its drv gets initialized, periodt.
