cpu/intel/car/non-evict/cache_as_ram.S: Add support for longmode

* Use heap for linker script calculated constant to fix relocation
  symbols in mixed assembly code.
* Work around a strange bug that causes the CPU to halt when accessing
  MMX registers in long mode

Tested on HPZ220:
* Still boots in x86_32.

Tested on Lenovo T410:
* Doesn't need the MMX register fix in long mode.
