drivers/intel/fsp2_0: Fix the FSP-T position
The only use case for FSP-T in coreboot is for 'Intel Bootguard' support at the moment. Bootguard can do verification FSP-T but there is no verification on whether the FSP found by walkcbfs_asm is the one actually verified as an IBB by Bootguard. A fixed pointer needs to be used. TESTED on OCP/Deltalake, still boots.
