In system suspend, the firmware pipelines will be deleted and there is no need to save the pipeline context. Driver will save the DPIB and LPIB pointers in suspend. In system resume, the firmware pipelines will be created again and the RD/RW pointers in the Firmware buffer points to the base address. So need to fetch the non-played data again to firmware buffer. LPIB indicates the HW rendered position. Instead of setting DPIB as resume point, set it to LPIB to restore from the HW render position so that DMA would fetch the non-played data one more time.
