Merge branch 'icc-mahua' into icc-next

Mahua is a derivative of the Glymur SoC and shares a significant
portion of its interconnect topology with Glymur. As such, this
series extends the existing Glymur interconnect driver to support
Mahua, reusing common definitions where possible and adding
SoC-specific configurations where necessary.
