Actually, it's either one or the other as they don't support the same
CPUs. iHD driver is for Broadwell or newer CPUs, and the i915 is for
older ones (Ice Lake is the first one it doesn't support). See

The fact that it's this confusing on the -devel list means it's going to be VERY confusing to end users. We need good documentation, which unfortunately has been one of our weak points, and it needs to be broadcasted everywhere.
