dmaengine: bam-dma: fix a warning about missing capabilities
Avoid the warning below triggered during dmaengine async device
registration.
WARNING: CPU: 1 PID: 1 at linux/drivers/dma/dmaengine.c:863
dma_async_device_register+0x2a8/0x4b8()
this driver doesn't support generic slave capabilities reporting
To do that fill mandatory .directions bit mask,
.src/dst_addr_widths and .residue_granularity dma_device fields
with appropriate values.
