sysmobts: Store a simple network config in the EEPROM as well
Make it possible to store:
* Static vs. DHCP mode
* IPv4 address
* Netmask
* GW IPv4 address
* DNS IPv4 address
Add a simple CRC8 and pick 0xFF as initial value so an all
zero EEPROM will not generate a 0 CRC. The code tries to
differentiate exit code between unreadable EEPROM and CRC error.
This is a reference to see if we want to have store it in the
EEPROM or not.
