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.

+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
+Documentation/hwmon/pmbus for details on PMBus client drivers.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write, history reset
+attributes are write-only, all other attributes are read-only.
+
+inX_label "voutx"
+inX_input Measured voltage.
+inX_min Minimum Voltage.
+inX_max Maximum voltage.
+inX_min_alarm Voltage low alarm.
+inX_max_alarm Voltage high alarm.
