Intel sch board & chip: Remove - using LATE_CBMEM_INIT
All boards and chips that are still using LATE_CBMEM_INIT are being removed as previously discussed. If these boards and chips are updated to not use LATE_CBMEM_INIT, they can be restored to the active codebase from the 4.7 branch. chips: soc/intel/sch Mainboards: mainboard/iwave/iWRainbowG6 Change-Id: Ida0570988a23fd0d13c6fcbe54f94ab0668c9eae Signed-off-by: Martin Roth <gaumless@gmail.com> Reviewed-on: https://review.coreboot.org/22027 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
