barner d4b3436d21 Add new plattform definition for the STK 501 board featuring an
Atmel ATmega128.

Very brief instructions:

- Configure your programmer etc. in Makefile.stk501
- Use 'make upload' to flash your STK501.
- Setup a SLIP connection to your board (on the first serial port)
  and make sure you can ping it.
- Use 'make loadable_prg.ko' to build a demo module.
- gcc -ocodeprop ../../tools/codeprop.c
- ./codeprop <IP of STK> loadable_prg.ko
- Watch the module print "Tick, Tack, Tick, ..." on the second
  serial port.
