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.
Changes since v3: - remove setting of gpio_chip->owner - format the mfr_status data - switch to #ifdef rather than #if IS_ENABLED for debugfs
Changes since v2: - split the gpio registration into it's own function
Changes since v1: - dropped dev_err messages - made gpio chip registration conditional on having gpio pins - made mfr_status debugfs attribute more simple
