staging: comedi: adv_pci_dio: Add a counter subdevice to PCI-1751 



The Advantech PCI-1751 has a 8254 counter chip on board.  Add it to the
device as a counter subdevice.  Apparently the counter can generate
interrupts although the driver does not currently use this capability.

Original patch by Ivan Russkih (Иван Русских) <vanekrus at gmail dot
