Sergio Rodriguez 381df63fe8 drivers: dma_qmsi: Wait few cycles to allow DMA controller changes 
Add few nop instructions to allow the DMA controller settle,
It takes time after starting the transfer to access the DMA
controller registers, so a few cycles are added, the minimal number
of cycles needed has been calculated using tests results on c1000
development board.
