dmaengine: Add note to dmatest documentation about supported channels



The documentation is not so clear for newbies in a sense of what type of the
channels are supported by it.

Clarify this by adding a note at the preamble of the documentation.

		This small document introduces how to test DMA drivers using dmatest module.

		.. note::
		The test suite works only on the channels that have at least one
		capability of the following: DMA_MEMCPY (memory-to-memory), DMA_MEMSET
		(const-to-memory or memory-to-memory, when emulated), DMA_XOR, DMA_PQ.
