thermal: allow u8500-thermal driver to be a module
When the thermal subsystem is a loadable module, the u8500 driver fails to build: drivers/thermal/built-in.o: In function `db8500_thermal_probe': db8500_thermal.c:(.text+0x96c): undefined reference to `thermal_zone_device_register' drivers/thermal/built-in.o: In function `db8500_thermal_work': db8500_thermal.c:(.text+0xab4): undefined reference to `thermal_zone_device_update' This changes the symbol to a tristate, so Kconfig can track the dependency correctly.
