hwmon: (nct6683) Add customer ID for ASRock Z590 Taichi

Add support for customer ID 0x1621 found on ASRock Z590 Taichi
boards using the Nuvoton NCT6686D embedded controller.

This allows the driver to instantiate without requiring the
force=1 module parameter.

Tested on two separate ASRock Z590 Taichi boards, both with
EC firmware version 1.0 build 01/25/21.
