dmaengine: dw-edma-pcie: Add capability match data

Move device-specific capability parsing behind per-device match data.

The existing probe path mixes two decisions: which static template a PCI
ID uses, and which device-specific capability parser adjusts that
template. Split those decisions so device-specific discovery can be
added through match data instead of adding more vendor checks to
dw_edma_pcie_probe().

No functional change is intended for the existing Synopsys EDDA and
AMD (Xilinx) MDB/CPM6 matches. They still copy the same static template
data and run the same capability parsing logic before BAR mapping. The
AMD (Xilinx) MDB/CPM6 entries also keep using endpoint memory physical
addresses for descriptor windows through a new match-data flag.
