mb/intel/mtlrvp: Enable EC for mtlrvp
This patch will initialize EC for mtlrvp which includes,
1. Add configuration (& choice) for CHROME_EC and INTEL_EC (WINDOWS_EC)
2. Add respective ACPI configuration
3. Add ec.c required for ramstage
4. Program EC ranges as part of devicetree.cb
5. Enable VBOOT in Kconfig
BUG=b:224325352
TEST=Able to build with the patch and boot the mtlrvp platform with
CHROME_EC using subsequent patches in the train
