usb: xhci: Add host support for eUSB2 double isochronous bandwidth devices

Detect eUSB2 double isoc bw capable hosts and devices, and set the proper
xhci endpoint context values such as 'Mult', 'Max Burst Size', and 'Max
ESIT Payload' to enable the double isochronous bandwidth endpoints.

Intel xHC uses the endpoint context 'Mult' field for eUSB2 isoc
endpoints even if hosts supporting Large ESIT Payload Capability should
normally ignore the mult field.
