From: Martin Botka <[e-mail]>

Add support for the thermal sensor found in H616 SoCs, is the same as
the H6 thermal sensor controller, but with four sensors.
Also the registers readings are wrong, unless a bit in the first SYS_CFG
register cleared, so set exercise the SRAM regmap to take care of that.
