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.
