ARM: edma: Add EDMA crossbar event mux support
EDMA supports a cross bar which provides ability to mux additional events into physical channels present in the channel controller. This is required when the number of events present in the system are more than number of available physical channels. Changes by Joel: * Split EDMA xbar support out of original EDMA DT parsing patch to keep it easier for review. * Rewrite shift and offset calculation.
