For bam2bam scenarios, the usb bam driver starts low power mode (lpm) after bus suspend or cable disconnect and after the handshake with the ipa peer bam is completed. So far, only msm otg state machine was responsible for setting the core into lpm. The problem is that in some race conditions, for example when disconnection of the pipes in usb bam happened sooner than the disconnection in the msm otg state machine, the lpm was started too soon by the usb bam, therefore caused a crash for accessing lpm HW by the msm otg. This change make sure that the usb bam will not start lpm unless the msm otg state machine has been tried to do so. In that case the usb bam will save this state as 'pending' lpm, and will start the lpm later in case the handshake with the ipa has not finished yet.
