Introduce an helper function to extract endpoint's max burst value.
Use this helper to calculate the Transfer Burst Count (TBC) and Transfer
Last Burst Packet Count (TLBPC) required for isochronous support.
Note that SS companion descriptors are still not read.
While here print the ETE and IST values in debug mode.
