msm: sps: SPS driver changes for dummy BAM connect

Added a flag (SPS_O_DUMMY_PEER) set by client,
based on the flag , passed destination and
destination pipe index values as peer bam values
and bypassed checks related to destination bam as
IPA bam is not present in this use case,
to support dummy bam connection from QDSS to IPA.
