soc/intel/ehl: Replace dt `HeciEnabled` by `HECI1 disable` config
The only option to make HECI1 function disable on Elkhart Lake SoC
platform is using SBI under SMM mode.
List of changes:
1. Drop `HeciEnabled` from dt and dt chip configuration.
2. Replace all logic that disables HECI1 based on the `HeciEnabled`
chip config with `DISABLE_HECI1_AT_PRE_BOOT` config.
Mainboards that choose to make HECI1 enable during boot don't override
`heci1 disable` config.
