soc/intel/common: Use CHIPSET_LOCKDOWN_COREBOOT by default

Since all mainboards use `CHIPSET_LOCKDOWN_COREBOOT`, make it the
default by changing its enum value to 0 and remove its configuration
from all related devicetrees.

If `common_soc_config.chipset_lockdown` is not configured with
something else in the devicetree, then `CHIPSET_LOCKDOWN_COREBOOT`
is used.

Also, add a release note for the upcoming 4.15 release.

 lots of code can now be shared. This should ease maintenance and also make it
 easier for newcomers to add support for even more mainboards.
 
+### Changed default setting for Intel chipset lockdown
+
+Previously, the default behaviour for Intel chipset lockdown was to let the FSP
+do it. Since all related mainboards used the coreboot mechanisms for chipset
+lockdown, the default behaviour was changed to that.
