Subject: [PATCH v2 1/2] thermal: Introduce CONFIG_QCOM_THERMAL in Makefile and qcom/Kconfig

Introduce CONFIG_QCOM_THERMAL to allow better control
over selection of various Qualcomm Thermal drivers
available inside qcom/ directory.

This is a preparatory change to allow new drivers to
be added inside qcom/ directory in a more structured
fashion later-on.
