USB: dwc3-msm: Initialize DBM ep before BAM pipe reset
On new platforms, endpoint clock gating is added for dbm endpoints
with Synopsys USB3.0 controller. This hardware feature requires
initialization of DBM endpoint before BAM pipe reset for bam2bam mode
data transfers working. Hence change sequence such that do DBM endpoint
initialization first followed by BAM pipe reset and do start transfer
as last operation.
