thermal: intel: Select INT340X_THERMAL from INTEL_SOC_DTS_THERMAL

The IRQ used by the Intel SoC DTS thermal device for critical
overheating notification is listed in _CRS of device INT3401 which
therefore needs to be enumerated for Intel SoC DTS thermal to work.

The enumeration happens by binding the int3401_thermal driver to the
INT3401 platform device. Thus CONFIG_INT340X_THERMAL is in fact
necessary for enumerating it, so checking CONFIG_INTEL_SOC_DTS_THERMAL
in int340x_thermal_handler_attach() is pointless and INT340X_THERMAL
may as well be selected by INTEL_SOC_DTS_THERMAL.
