Subject: [PATCH 2/3] thermal: amlogic: Support C3 thermal controller driver

From: Xianwei Zhao <xianwei.zhao@...ogic.com>

Add the thermal controller driver for the C3 SoC family.

The main difference compared to other Amlogic chips lies in the
offset of the sec_ao base (referred to as u_efuse_off), which is
handled differently. Everything else remains consistent.
