John Crispin 25afe99b31 mediatek: add support for the new MT7623 Arm SoC
the support is still WIP. next steps are to make the pmic and ethernet work.
this is the first commit to make sure nothing gets lost.

Subject: [PATCH 13/76] thermal: Use IS_ENABLED instead of #ifdef
Use IS_ENABLED(CONFIG_THERMAL_EMULATION) to make the code more readable
and to get rid of the addtional #ifdef around the variable definitions
in thermal_zone_get_temp().
