dmaengine: imx-sdma: Declare slave capabilities for the generic code

Browse source 
Since ecc19d1786 ("dmaengine: Add a warning for drivers not using the
generic slave caps retrieval") the following warning is observed:

[    0.224981] ------------[ cut here ]------------
[    0.225013] WARNING: CPU: 0 PID: 1 at drivers/dma/dmaengine.c:830 dma_async_device_register+0x2a0/0x4c8()
[    0.225023] this driver doesn't support generic slave capabilities reporting

Declare the slave capabilities to avoid such warning.
