dma: Add Synopsys eDMA IP driver (version 0)

Add Synopsys eDMA IP driver (version 0) to Linux kernel. This IP is generally distributed with Synopsys PCIe EndPoint IP (depends of the use and licensing agreement), which supports:
- legacy and unroll modes
- 16 independent and concurrent channels (8 write + 8 read)
- supports linked list (scatter-gather) transfer
- each linked list descriptor can transfer from 1 byte to 4 Gbytes
- PCIe EndPoint glue-logic
