docs: hwmon: Add an index file and rename docs to *.rst
Now that all files were converted to ReST format, rename them
and add an index.

However, most -standard PMBus commands are not supported. Specifically, all hardware monitoring -and status reporting commands are non-standard. For this reason, a standard -PMBus driver can not be used. - - -Usage Notes ------------ - -This driver does not probe for Lineage CPL devices, since there is no register -which can be safely used to identify the chip. You will have to instantiate -the devices explicitly. - -Example: the following will load the driver for a Lineage PEM at address 0x40 -on I2C bus #1:: - - $ modprobe lineage-pem - $ echo lineage-pem 0x40 > /sys/bus/i2c/devices/i2c-1/new_device - -All Lineage CPL power entry modules have a built-in I2C bus master selector -(PCA9541).
