thermal: st: fix Makefile typo

When STM32_THERMAL is enabled, this overrides all previously
enabled files in the same directory, as seen from this link failure:

ERROR: "st_thermal_pm_ops" [drivers/thermal/st/st_thermal_syscfg.ko] undefined!
ERROR: "st_thermal_register" [drivers/thermal/st/st_thermal_syscfg.ko] undefined!
ERROR: "st_thermal_unregister" [drivers/thermal/st/st_thermal_syscfg.ko] undefined!

The correct syntax in Makefile requires using += instead of :=.
