[PATCH] Add or1ksim (sim.cfg) configuration file and edit README.

[Hesham ALMatary]

OpenRISC/or1ksim BSP: The new sim.cfg file configures or1ksim emulator with HW
capabilities that the current RTEMS/or1ksim BSP supports.

README: HOWTO run the or1ksim simulator.

+The current sim.cfg file that configures or1ksim emulator to RTEMS/or1ksim BSP
+is at the same directory as this README. You can also use or1ksim script from 
+rtems-tools/sim-scripts.

+sim -f sim.cfg $PATH_TO_RTEMS_EXE

+or32-elf-sim -f sim.cfg $PATH_TO_RTEMS_EXE

+or1ksim $PATH_TO_RTEMS_EXE
