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.

As this touches a core Thermal file, I think it's better off going in
via that tree.  If that's a problem, I can take it with the relevant
Acks.

Thanks, I am adding to linux-next to see how it goes.
