hwmon: (pmbus) Add support for ADM1266 Add pmbus probing driver for the adm1266 Cascadable Super Sequencer with Margin Control and Fault Recording. Driver is using the pmbus_core, creating sysfs files under hwmon for inputs: vh1->vh4 and vp1->vp13.

Kernel driver adm1266
=====================
Supported chips:
* Analog Devices ADM1266
Prefix: 'adm1266'
Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ADM1266.pdf
Author: Alexandru Tachici <alexandru.tachici@analog.com>
Description
-----------
This driver supports hardware monitoring for Analog Devices ADM1266 sequencer.
ADM1266 is a sequencer that features voltage readback from 17 channels via an
integrated 12 bit SAR ADC, accessed using a PMBus interface.
The driver is a client driver to the core PMBus driver. Please see
docs: hwmon: adm1266.rst: fix a broken reference The reference was missing the extension, causing the check script to complain.
