Intel i82830 boards & chips: 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:
cpu/intel/socket_mFCBGA479
northbridge/intel/i82830

Mainboards:
mainboard/rca/rm4100
mainboard/thomson/ip1000
