The HDMA IP supports the HDMA_NATIVE map format as part of Vendor-Specific
Extended Capability. Added the check for HDMA_NATIVE map format.
The check for map format enables the IP specific function invocation
during the DMA ops.

You also need to update the 'Debug info' part in dw_edma_pcie_probe().
