This thing that a Kconfig symbol is made to depend on itself just
boggles my head but it wouldn't surprise me if KConfig is this weird :(

I CCed Arnd who knows KConfig a bit better than anyone I know.

Sorry but I don't see a dependency on itself here.

"IIO_ST_ACCEL_I2C_3AXIS" depends on "IIO_ST_ACCEL_3AXIS"

Name with I2C embedded not at end could be a bit wired, but in this patch I don't change any names to keep things 100% backward-compatible.
