hwmon: (ltc2992) Add support

LTC2992 is a rail-to-rail system monitor that
measures current, voltage, and power of two supplies.

Two ADCs simultaneously measure each supply’s current.
A third ADC monitors the input voltages and four
auxiliary external voltages.

Description
-----------
This driver supports hardware monitoring for Linear Technology LTC2992 power monitor.
LTC2992 is a rail-to-rail system monitor that measures current,
voltage, and power of two supplies.
Two ADCs simultaneously measure each supply’s current. A third ADC monitors
the input voltages and four auxiliary external voltages.

If you say yes here you get support for Linear Technology LTC2992
I2C System Monitor. The LTC2992 measures current, voltage, and
power of two supplies.
This driver can also be built as a module. If so, the module will
be called ltc2992.
