DSDT.asl should not report the AMD SB600/SB700 RTC as Intel PIIX4
compatible. The extended cmos is accessed differently for AMD
and Intel RTCs. Not sure what if any OS cares about this distinction,
but non-Intel compatible seems like a safer way to report the AMD RTC.
Tested with Win7 on Mahogany_fam10 and kino-780am2-fam10.
