psu-ng: Add ACBEL PSU pmbus supported commands.

Update PSU monitor to use the following pmbus commands supported
by ACBEL PSU DD:

 - To clear STATUS_INPUT use curr1_crit_alarm instead of
   in1_crit_alarm fault.
 - Update ACBEL PSU firmware version to be read from
   /sys/kernel/debug/pmbus/hwmonX instead from
   /sys/kernel/debug/pmbus/hwmonX/3-005a/ and update the ACBEL
   FW version size to 6 bytes.
 - On/off config not supported on ACBEL PSU.

Testing:
* Unplugged power cord from the ACBEL PSU, and verified an error
  reported on the system.
* Set IIN_OC_FAULT_LIMIT fault and verified curr1_crit_alarm clears
  the STATUS_INPUT.
* Verified the code reading the ACBEL FW revision correctly.
* Verified in1_input clears all faults on ACBEL PSU.
* Tested modified the code on IBMCFFPS and verified the ACBEL PSU
  modification did not change the behavior on IBMCFFPS.
