coreboot t132: Stack init re-work
1) In order to avoid stack from overflowing during ramstage decompression,
initialize stack right at the beginning of romstage.
2) Declare different Kconfig options for stack at each stage.
3) Provide a macro that does stack seeding if required and calls appropriate
function.
