Ian Lepore 0c1daec859 Eliminate the last dregs of the old global arm_root_dma_tag. ... In the old days, device drivers passed NULL for the parent tag when creating a new tag, and on arm platforms that resulted in a global tag representing overall platform constraints being substituted in the busdma code. Now all drivers use bus_get_dma_tag() and if there is a need to represent overall platform constraints they will be inherited from a tag supplied by nexus or some bus driver in the hierarchy. The only arm platforms still relying on the old global-tag scheme were some xscale boards with special PCI-bus constraints. This change provides those constraints through a tag supplied by the xscale PCI bus driver, and eliminates the few remaining references to the old global var.
