usb: bam: Return usb_pipe_mem_type from get_bam2bam_connection_info()

Some functions may need to know the pipe memory type, whether it
is allocated memory or a private region of internal peripheral
memory. Add an extra parameter to the get_bam2bam_connection_info()
function to return this value based on the preconfigured BAM pipes.

For most functions this info is unneeded. For QDSS, use this value
to determine whether to pass MSM_INTERNAL_MEM to the SPS params
when running on a device that requires it.
