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.
