rt2800: add eFuse EEPROM support code to rt2800lib
eFuse EEPROM is used also by USB chips (i.e. RT3070) so move the needed code from rt2800pci to rt2800lib. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
