B450/X399 boards:
* ROG CROSSHAIR VI HERO,
* PRIME X399-A,
* PRIME X470-PRO,
* ROG CROSSHAIR VI EXTREME,
* ROG CROSSHAIR VI HERO (WI-FI AC),
* ROG CROSSHAIR VII HERO,
* ROG CROSSHAIR VII HERO (WI-FI),
* ROG STRIX B450-E GAMING,
* ROG STRIX B450-F GAMING,
* ROG STRIX B450-I GAMING,

* ROG STRIX X470-F GAMING,
* ROG STRIX X470-I GAMING,
* ROG ZENITH EXTREME,
* ROG ZENITH EXTREME ALPHA.

There is at least one more sensor hiding in the EC address space: the
south bridge voltage. And it seems its value is not an integer, so the
conversion to mV will not be a simple get_unaligned_xx() call when we
locate and add it.

@Eugene Shalygin: I have updated patch with usage separate function for 
convert binary data to sensors value as you proposed for sensors with 
sophisticated logic. Also I have moved quiery creation logic to sensors 
setup function.

@Guenter Roeck: I have added both sensors to index.rst, fixed usage of 
acpi_os_free in asus_wmi_ec_block_read and fixed 'instrnal' typo in both 
files.

Could you please review?

- Add asus_wmi_sensor to documentation index.
- Add asus_wmi_ec_sensor to documentation index.

Changes in v5:
- Fixes build issue reported by kernel test robot with disabled ACPI_WMI.
- asus_wmi_sensors: Remove sensor->name check as always evaluated to true.

Changes in v4:
 - Implement wmi driver instead platform driver.
 - Update documentation with known issues.

Changes in v3:
 - Use MODULE_DEVICE_TABLE for match devices.

Changes in v2:
 - asus_wmi_ec_sensors: Rename asus_wmi_sensors to asus_wmi_ec_sensors for 
   B550/X570 boards.
 - asus_wmi_ec_sensors: Use utf8s_to_utf16s/utf16s_to_utf8s instead handmade 
   fuctions.
 - asus_wmi_ec_sensors: Use post increment.
 - asus_wmi_ec_sensors: Use get_unaligned* for convert values.
 - asus_wmi_ec_sensors: Use PTR_ERR_OR_ZERO.
 - asus_wmi_ec_sensors: Specify per-board sensors in a declarative way 
   (by Eugene Shalygin).
 - asus_wmi_sensors: Add support for X370/X470/B450/X399 boards.
