soc/intel/cnl: replace the remaints of HeciEnabled by device state in dt

The option `HeciEnabled` was partly replaced by use of the device on/off
state in the devicetree in commit 3de90d1. The option has been removed
from the corresponding boards, so `HeciEnabled` is always 0 and ME gets
always gets disabled during soc finalize, when `HECI_DISABLE_USING_SMM`
is set.

Replace the option in the finalize function by the same dt state check
that sets the FSP option and drop the remaints of `HeciEnabled`.

Devicetrees still having `HeciEnabled` have been adapted to keep the
current behaviour.
