qlcnic: Support VF-PF communication channel commands.

o Add support for commands from VF to PF.
o PF validates the commands sent by the VF before sending
  it to adapter.
o vPort is a container of resources. PF creates vPort
  for VFs and attach resources to it. vPort is
  transparent to the VF.
o Separate 83xx TX and RX hardware resource cleanup from 82xx.
