The sun4i-ts driver has had a dependency on the thermal code

The "since it was first merged bit" is not true, this is caused
by recent changes by ChenYu.
Other then that no objections from me against the proposed fix.

but this is not currently enforced
in Kconfig, so in some randconfig builds we get
drivers/built-in.o: In function `sun4i_ts_remove':
:(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister'
drivers/built-in.o: In function `sun4i_ts_probe':
:(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register'
:(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'
We need the dependency on THERMAL in order to ensure that this
driver becomes a loadable module if the thermal support itself
is modular, while the dependency on THERMAL_OF is a runtime dependency
and the driver will still build but not work if it is missing.
