dmaengine: shdma: Make second memory window optional
This patch makes the shdma.c driver allow slave operation
on DMA hardware mapped with a single I/O-memory window.
The dmae_set_dmars() function is adjusted to use the
first memory window in case of a missing DMARS window.
At probe() time the code is updated to enable DMA_SLAVE
only if slave information is passed with the platform data.
