dmaengine: mxs-dma: Declare slave capabilities for the generic code
Since ecc19d17868be9c ("dmaengine: Add a warning for drivers not using the
generic slave caps retrieval") the following warning is observed:
[ 0.113023] ------------[ cut here ]------------
[ 0.113053] WARNING: CPU: 0 PID: 1 at drivers/dma/dmaengine.c:830 dma_async_device_register+0x2a0/0x4c8()
[ 0.113063] this driver doesn't support generic slave capabilities reporting
Declare the slave capabilities to avoid such warning.
