soc/intel/{cnl,icl,skl, tgl}: Move SOC_INTEL_COMMON_BLOCK_THERMAL into SoC specific Kconfig

This patch moves common pch code SOC_INTEL_COMMON_BLOCK_THERMAL Kconfig selection
into SoC specific Kconfig selection as PCH thermal device is not available
with latest PCH (i.e. TGP and JSP).

Also added TODO for TGL thermal configuration as applicable.

TEST=Able to build and boot TGL RVP with this CL
