dmaengine: dw-edma-pcie: Add register offset match flag

Add a match-data flag for devices whose DMA register block starts at an
offset inside the mapped BAR. Existing Synopsys EDDA and AMD (Xilinx)
MDB/CPM6 matches keep using the BAR mapping base directly.

The offsets handled here come from static, trusted match data. Later
metadata-derived offsets are validated when the endpoint DMA metadata
path parses them at that trust boundary.

No functional change intended.
