Small SMM fixups

Align the spinlock to the 4 byte boundary (CPU will guarantee atomicity of XCHG).
    While at it add the PAUSE instruction to spinlock loop to hint the CPU we are just
    spinlocking. The rep nop could not be used because "as" complains that rep is used
    without string instructions.
