hwmon: add support for sensors exported via ARM SCMI

Browse Source 
Create a driver to add support for SoC sensors exported by the System
Control Processor (SCP) via the System Control and Management Interface
(SCMI). The supported sensor types is one of voltage, temperature,
current, and power.

The sensor labels and values provided by the SCP are exported via the
hwmon sysfs interface.

This driver provides support for temperature, voltage, current
and power sensors available on SCMI based platforms. The actual
number and type of sensors exported depend on the platform.
This driver can also be built as a module. If so, the module
will be called scmi-hwmon.
