dmaengine: dw: properly read DWC_PARAMS register commit 6bea0f6d1c47b07be88dfd93f013ae05fcb3d8bf upstream. In case we have less than maximum allowed channels (8) and autoconfiguration is enabled the DWC_PARAMS read is wrong because it uses different arithmetic to what is needed for channel priority setup. Re-do the caclulations properly. This now works on AVR32 board well.
