[PATCH 6.19 230/844] hwmon: (nct6683) Add customer ID for ASRock Z590 Taichi

[Sasha Levin]

From: Anj Duvnjak <avian@xxxxxxxxxxxxxxxx>

[ Upstream commit c0fa7879c9850bd4597740a79d4fac5ebfcf69cc ]

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.
