A user discovered that the Geniatech x8000 encountered a regression when the xc3028 power management was introduced. The xc3028 never recovers after setting the powerdown register, which is probably because the xc3028 reset GPIO is not properly configured. Since I do not have access to the hardware and thus cannot determine the correct GPIO configuration, just disable xc3028 power management on this board, which fixes the regression. Thanks to user "ritec" for reporting the issue and testing the fix.
