[LinuxBIOS] CK804 suggestions

Your approach only allows the MAC address to be in the EEPROM or the romstrap.  Every motherboard would have to put the EEPROM in exactly the same place for this to be a general solution.  Not likely.  
Neither place is a general solution.   
Getting the MAC address is board specific and belongs in mainboard.

don't need, 
1. good hw design should use one serial EEPROM to store MAC address, So when
flash the BIOS, the EEPROM is still there.
	in ck804_nic.c will read MAC from serial EEPROM in SMBUS (bus num
and device num is set in Mainboard Config.lb), at first.
2. even for bad design, you can keep your own romstrap.inc/lds in your
mainboard dir, and modify Config.lb to point corrent file.
	In such case, you need special flash util to keep your MAC address
or read the MAC address at first, and then set it back....
