usb: bam: suspend/resume handshake with the IPA

When going to suspend, there is the need to perform
a handshake with the IPA. Furthermore, due to a
hardware bug in the DBM, there is also a need to
reset the DBM ep and corresponding BAM pipe.

This patch exposes the need (or lack thereof) to perform
the DBM and BAM reset, as well as incorporates this reset
into the overall flow of handshaking with the IPA
