soc/intel/cannonlake: Add TDC config for CML
Add Thermal Design Current (TDC) defaults for CML:
1. TdcEnable
2. TdcPowerLimit
BUG=b:148912093
BRANCH=None
TEST=build coreboot and Intel FSP with fw_debug enabled, flash image to
the device, capture the log from the serial port during boot-up and
check TdcEnable and TdcPowerLimit for each domain in captured log
