drivers/intel/fsp2_0: Make coreboot FSP stack 16-bytes aligned
- Stack alignment:
1. FSP functions must be called with the stack 16-bytes aligned in x86_64 mode.This is already setup properly with the default value of the `mpreferred-stack-boundary' compiler option (4). Similarly for x86_32 it is set to 2 through compiler option.
2. The FSP heap buffer supplied by coreboot through the `StackBase' UPD must be 16-bytes aligned for x86_64 and 4-bytes aligned for x86_32.
