dmaengine: dw-edma-pcie: Handle optional data blocks
Skip data block BAR mapping and debug output when a channel has no data
block size. This lets future providers describe channels that only need
descriptor memory exposed.
No functional change intended for existing Synopsys EDDA and
AMD (Xilinx) MDB/CPM6 devices. Their static channel descriptions still
provide data block sizes where data block windows are used. A zero-sized
data block now means "not present" for future metadata providers.
