x86: Handle overlapping mptables
We found a system where the MP table MPC and MPF structures overlap. That doesn't really matter because the mptable is not used anyways with ACPI, but it leads to a panic in the early allocator due to the overlapping reservations in 2.6.33. Earlier kernels handled this without problems. Simply change these reservations to reserve_early_overlap_ok to avoid the panic.
