topology: Add nocodec SAI topology for i.MX8QXP 

i.MX8QXP has one SAI interface. Create a simple topology
without a codec for playback of 2 channels, 16bits samples
at 48Khz.

Host -> Buffer0 -> Volume -> Buffer1 -> SAI1

This is useful for testing various components like Dummy DMA,
EDMA and SAI drivers.

For more information about SAI you can read i.MX8QXP RM at:
