dmaengine: dw-edma: Detach the private data and chip info structures
"struct dw_edma_chip" contains an internal structure "struct dw_edma" that
is used by the eDMA core internally and should not be touched by the eDMA
controller drivers themselves. But currently, the eDMA controller drivers
like "dw-edma-pci" allocate and populate this internal structure before
passing it on to the eDMA core. The eDMA core further populates the
structure and uses it. This is wrong!
Hence, move all the "struct dw_edma" specifics from controller drivers to
the eDMA core.
