drivers/intel/fsp2_0: Support FSP 2.4 64-bits

FSP 2.4 brings FSP 64-bits support which requires some adjustments in
coreboot:

  FSP/UEFI uses the Microsoft x64 calling convention. Appropriate
  attribute has to be set to all functions calling or called by
  the FSP.

BUG=b:329034258
TEST=verified on Lunar Lake RVP board (lnlrvp)
