Remove the call to dev_info() from the board detection function, which
is called from probe(), not only to be in line with hwmon driver rules, but
also because the message duplicates the error code returned from probe()
for that case (ENODEV).
Changes in:
- v2: add missing newline (style).

Merge configure_sensor_setup() into probe().
Changes:
- v2: add local struct device *dev = &pdev->dev;
- v3: initialize dev at declaration
- v4: fix checkpatch warning
- v5: fix formatting
- v6: code style fixes

Reading DSDT code for ASUS X470-based boards (the ones served by the
asus_wmi_Sensors driver), where ASUS put hardware monitoring functions
into the WMI code, reveals that fan and current sensors data is
unsigned. For the current sensor that was confirmed by a user who showed
high enough current value for overflow.
Thus let's assume that the signedness of the sensors is determined by its
type and that only temperature ones provide signed numbers.

A user discovered [1] the CPU Core voltage sensor, which spans 2
registers and provides output in mV. Althroug the discovery was made
with a X470 chipset, the sensor is present in X570 (tested with C8H).
For now simply add it to each board with the CPU current sensor present.

Temperature sensor readings are signed, which is hinted by their blank
value (oxd8, 216 as unsigned and -40 as signed). T_Sensor, Crosshair
VIII Hero, and a freezer were used to confirm that.
Here we read fan sensors as signed too, because with their typical
values and 2-byte width, I can't tell a difference between signed and
unsigned, as I don't have a high speed chipset fan.

There is no such struct as "asus_ec_sensors", it was supposed to be
"ec_sensors_data". This typo does not affect either build or runtime.

The Wi-Fi variant of Crosshair VIII Hero provides the same sensors,
which was tested by a Libre Hardware Monitor user [1].

This driver provides the same data as the asus_wmi_ec_sensors driver
(and gets it from the same source) but does not use WMI, polling
the ACPI EC directly.
That provides two enhancements: sensor reading became quicker (on some
systems or kernel configuration it took almost a full second to read
all the sensors, that transfers less than 15 bytes of data), the driver
became more flexible. The driver now relies on ACPI mutex to lock access
to the EC in the same way as the WMI code does.
