sis190: read the mac address from the eeprom first
upstream commit: 563e0ae06ff18f0b280f11cf706ba0172255ce52
Reading a serie of zero from the cmos sram area do not work
well with is_valid_ether_addr(). Let's read the mac address
from the eeprom first as it seems more reliable.
Fix for http://bugzilla.kernel.org/show_bug.cgi?id=9831
