(Busybox i2cset is from the stone ages). You could use debugfs, if you looking in drivers/base/regmap/regmap-debugfs.c and change the undef to a define for REGMAP_ALLOW_WRITE_DEBUGFS. Then you can write registers by echoing register value pairs to the the registers file in debugfs. Be careful though this is only intended for testing and as the define makes all regmaps writable from user-space depending on your system that may let you do things that damage hardware.
