parisc: ccio-dma: Create private runway procfs root entry
Create an own procfs "runway" root entry for the CCIO driver.
No need to share it with the sba_iommu driver, as only one
of those busses can be active in one machine anyway.

Fixes: 547259580dfa ("parisc: Move proc_mckinley_root and proc_runway_root to sba_iommu")
