dmaengine: dw-edma-pcie: Factor out descriptor block address lookup

Browse source

Add an optional physical address override to struct dw_edma_block and
use a helper to compute descriptor block addresses.

No functional change intended. Existing Synopsys EDDA and AMD (Xilinx)
MDB/CPM6 block descriptors leave the override unset, so the helper still
returns the same values as before.
