x86: Merge early kernel reserve for 32bit and 64bit
They are the same, and we could move them out from head32/64.c to setup.c. We are using memblock, and it could handle overlapping properly, so we don't need to reserve some at first to hold the location, and just need to make sure we reserve them before we are using memblock to find free mem to use.
