usb-ehci: drop assert()

Not sure what the purpose of the assert() was, in any case it is bogous.
We can arrive there if transfer descriptors passed to us from the guest

usb-ehci: frindex always is a 14 bits counter

frindex always is a 14 bits counter, and not a 13 bits one as we were
emulating. There are some subtle hints to this in the spec, first of all
"Table 2-12. FRINDEX - Frame Index Register" says:
"Bit 13:0 Frame Index. The value in this register increments at the end of...

usb: add USBDescriptor, use for device descriptors.

descriptors. It is put into use for the descriptor generator code
where the struct replaces the hard-coded offsets.

usb-host: rewrite usb_linux_update_endp_table

This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:

  • We are using the USBDescriptor struct instead of hard-coded offsets
    now to access descriptor data.
  • (debug) printfs are all gone, tracepoints have been added instead....

usb-ehci: Drop unused sofv value

The sofv value only ever gets a value assigned and is never used (read)
anywhere, so we can just drop it.
