soc/intel/tigerlake: Change compilation based on TIGERLAKE_BASE

since we support JSL and TGL soc under tigerlake folder, we need to make
sure all soc related files get compiled based on
CONFIG_SOC_INTEL_TIGERLAKE_BASE and not only for Tigerlake.

We can control soc specific file compilation through Kconfig of
individual soc.
