Fixes & improvements in virtual hub

The changes includes:

  • unified (a bit) debugging output
  • port is put into power-off state after SET_CONFIGURATION request
  • less ports on the hub
  • delayed port changes run in separate fibril
  • shorter waiting for transactions in HC scheduling manager
