Kedareswara rao Appana 21e02a3e05 dmaengine: xilinx_dma: Check for channel idle state before submitting dma descriptor ...

Add variable for checking channel idle state to ensure that dma
descriptor is not submitted when dmaengine is in progress.

This will avoid the polling for a bit in the status register to know
dma state in the driver hot path.
