thermal/drivers/sun8i: Add support for H616 THS controller

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.
