[RFC PATCH 3/3] hw/cxl/cxl-device-utils: Allow incorrect read lengths

[Jonathan Cameron]

This is currently needed to avoid an issue in the Linux RFC
in which a read is issued that is not a multiple of DW.
On arm64 that results in byte reads being issued and a bus
error returned.

It is not yet obvious at what level this should be fixed,
so paper over it to get things working.
