northbridge/intel/sandybridge/raminit: Prepare MRC path for x86_64

- Remove pointers in argument list passed to MRC to make sure the struct
  has the same size on x86_64 as on x86_32.
- Add assembly wrapper to call the MRC with argument in EAX.
- Wrap calling MRC in protected_mode_call_2arg, which is a stub on x86_32

Tested: Boots on Lenovo X220 using MRC in x86_32 and x86_64 mode.
