drivers/intel/fsp: Work around multi-socket Xeon-SP pipe init bug

Starting with Intel CPX there is a bug in the reference code during
the Pipe init. This code synchronises the CAR between sockets in FSP-M.
This code implicitly assumes that the FSP heap is right above the
RC heap, where both of them are located at the bottom part of CAR.

Work around this issue by making that implicit assumption done in FSP
explicit in the coreboot linker script and allocation.
