The ucd9000 series chips have gpio pins. Add a gpio chip interface to the ucd
device so that users can query and set the state of the gpio pins.
Add a debugfs interface using the existing pmbus debugfs directory to provide
MFR_STATUS and the status of the gpi faults to users.

while on the ast2500 the chip selects are swapped.
Also clear the secondary boot bit during the machine restart operation.
Otherwise, the system will switch to the alternate boot after every
