feat(gic600ae_fmu): disable SMID for unavailable blocks
This patch updates the gic600_fmu_init function to disable all safety
mechanisms for a block ID that is not present on the platform. All
safety mechanisms for GIC-600AE are enabled by default and should be
disabled for blocks that are not present on the platform to avoid
false positive RAS errors.
