dmaengine: dw: Split DW and iDMA 32-bit operations
Here is a kinda big refactoring that should have been done in the first place, when Intel iDMA 32-bit support appeared. It splits operations which are different to Synopsys DesignWare and Intel iDMA 32-bit controllers. No functional change intended.
