hwmon: (asus_wmi_ec_sensors) remove driver

This driver utilises a WMI interface found in AMD 500 series ASUS boards,
to read EC registers. But it turned out that ASUS abandoned the
interface, as it disappeared from Intel 600 series boards. Additionally,
the WMI interface was incredibly slow. Therefore this driver was deprecated
in favor of the asus_ec_sensors driver, which supports more boards, more
sensors, and is faster.

-Description:
-------------
-ASUS mainboards publish hardware monitoring information via Super I/O
-chip and the ACPI embedded controller (EC) registers. Some of the sensors
-are only available via the EC.
-
-ASUS WMI interface provides a method (BREC) to read data from EC registers,
-which is utilized by this driver to publish those sensor readings to the
-HWMON system. The driver is aware of and reads the following sensors:
-
-1. Chipset (PCH) temperature
-2. CPU package temperature
-3. Motherboard temperature
-4. Readings from the T_Sensor header
-5. VRM temperature
-6. CPU_Opt fan RPM
-7. Chipset fan RPM
-8. Readings from the "Water flow meter" header (RPM)
-9. Readings from the "Water In" and "Water Out" temperature headers
-10. CPU current
