This patchset replaces the HWMON asus_wmi_ec_sensors driver with
an implementation that does not use WMI but queries the embedded
controller 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 fexible. The driver now relies on ACPI mutex to lock access
to the EC, in the same way as the WMI DSDT code does.

Changes in v6:
 - Fixed hwmon device name replacing dashes with underscores.
 - Removed module verion.
 - Fixed condition for asus_wmi_ec_Sensors in KBuild.

Changes in v5:
 - Place the sensors bitset directly into the driver_data field of the
         dmi_system_id struct.
 - Replace doc comments with regular ones.

Changes in v4:
 - Deprecate the wmi driver rather than removing it.

Changes in v3:
 - Remove BIOS version checks and BIOS version dependent mutex path.

Changes in v2:
 - Replace sensor flags enum with bitset
 - Replace module init/probe functions with module_platform_driver_probe
   and ask the platform drivers framework to load the driver when ACPI
   EC is found (ACPI ID "PNP0C09").
 - Extend board data with BIOS version attribute for the mutex path to be
   BIOS version dependent.
 - Add module parameter to override the mutex path.
