patch for smsc lan91cxx ethernet driver

The patch works. My hardware specific part of the driver now uses:

requires CYGNUM_DEVS_ETH_SMSC_LAN91CXX_INT_PRIO >= 0
requires CYGNUM_DEVS_ETH_SMSC_LAN91CXX_INT_PRIO <= 7

in order to ensure that the value is in the allowed range from 0-7 for
EDOSK-2674 interrupts.

Thank you very much.
