ramstage: Align stack to 16 bytes
Some SSE instructions could take 128bit memory operands from
stack.
AGESA vendorcode was always built with SSE enabled, but until
now stack alignment was not known to cause major issues. Seems
like GCC-6.3 more likely emits instructions that depend on the
16 byte alignment of stack.
