Revert "soc: qcom: bam_dmux: Use SPS atomic allocation flag"

Bam_dmux sometimes calls sps_connect() during time sensitive operations.
Sps_connect() internally has some memory allocations which may stall
during low memory conditions and can cause a timeout in bam_dmux
SPS supports a configuration flag which changes these memory allocations
to atomic. Use this flag to prevent allocations from stalling and
leading to timeouts.

Additional flag added is resulting in error instead of timeout.
Reverting change Icde45f7b08a4b4a2b664c40d088fd338b48ac8fa as the issue
is not solved. Commit id d2393c2628fd88e1a882ca4a6c23c9eb68f42bb8.
