Log:
Fix power_on_after_fail handling on AMD SB600
Bit 0 of pm reg#74 have to be set turn on system after power resumes.
See '42661_sb600_rrg_nda_3.02.pdf' (or '46155_sb600_rrg_pub_3.03.pdf')
for details, look for 'PwrFailShadow'.
[Patrick: I didn't include the get_options reorganization as get_option
doesn't overwrite "on" if power_on_after_fail isn't found in CMOS.
Style changes were also left out.]
