This adds support for the Mediatek thermal controller found on MT8173
and likely other SoCs.
The controller is a bit special. It does not have its own ADC, instead
it controls the on-SoC AUXADC via AHB bus accesses. For this reason
we need the physical address of the AUXADC. Also it controls a mux
using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.

Hanyi Wu ?

It's the original author of this code.

Sorry I wasn't clear. I was suggesting to remove the dot between Hanyi and Wu.

+#define TEMP_MONINT_COLD(sp) (BIT(0) << ((sp) * 5))
+#define TEMP_MONINT_HOT(sp) (BIT(1) << ((sp) * 5))

+#define TEMP_PROTCTL_AVERAGE (0 << 16)

<-- Not used.

Will remove.

Sascha
