[ Upstream commit 4d2f1794c07aae55b8f25f4d8aebcafc0d3e501d ]
When the thermal subsystem is a loadable module, the spear driver fails to build:
drivers/thermal/built-in.o: In function `spear_thermal_exit': spear_thermal.c:(.text+0xf8): undefined reference to `thermal_zone_device_unregister' drivers/thermal/built-in.o: In function `spear_thermal_probe': spear_thermal.c:(.text+0x230): undefined reference to `thermal_zone_device_register'
This changes the symbol to a tristate, so Kconfig can track the dependency correctly.
