drivers/intel/fsp2_0: Add limited to 32-bits FSP 2.4 support
Intel Firmware Support Package 2.4 specification (document 736809)
brings some significant changes compared to version 2.3 (document
644852):
1. It supports FSP-M multi-phase init. Some fields have been added to
the FSP header data structure for this purpose.
2. The `FSPM_ARCH2_UPD' and `FSPS_ARCH2_UPD' data structures must be
used in place of `FSPM_ARCH_UPD' and `FSPS_ARCH_UPD' respectively.
3. It support 64-bits FSP but 64-bits support will be provided by
subsequent patch.
Note that similarly to what is done for silicon initialization,
timestamps and post-codes are used during the memory initialization
multi-phase.
