soc/intel/common: add TCC activation functionality
This enables to configure the Thermal Control Circuit (TCC) activation
value to new value as tcc_offset in degree Celcius. It prevents any
abrupt thermal shutdown while running heavy workload. This helps to
take early thermal throttling action before CPU temperature reaches
maximum operating temperature TjMax value. Also, cleanup local functions
from previous intel soc specific code base like for apollolake, broadwell,
skylake and cannonlake.
BUG=None
BRANCH=None
TEST=Built for volteer platform and verified the MSR value.
