No, this just isn't true in general - if a device has trouble with bulk
reads it needs to set use_sigle_rw in the config to disable them.
Device limitations with bulk reads are a per device thing and are
orthogonal to the value size, being more to do with the age and quality
of the register map implementation than anything else.
