  Debugfs operations may set the page number, which must be done
atomically with the subsequent i2c operation. Lock the update_lock
in the debugfs functions and provide a function for pmbus drivers
to lock and unlock the update_lock.
Use the new lock/unlock functions in the ibm-cffps driver and make
some additional improvements.
