Coreboot uses the compiler option -mregparm=3 which causes variables to
be passed in registers. This is good for size and speed but not good when
we call a C function from asm. Force stage1_phase1 to use stdcall and get
variables off the stack.
Note that I didn't change stage1_phase3 because it doesn't use any
variables.
