usb: bam: Add max Mbps vote for IPA resources

Add a vote for IPA clock performance to enhance IPA clock
tuning according to the actual connection speed in use cases
which involve USB or HSIC connection to IPA.

For Bam2Bam mode we support USB high speed or super speed only, in each
there is different limitation of max mbps, therefore allow tuning
performance upon connection establishment.
