hwmon: (asus-ec-sensors) add CPU core voltage
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.
