[TF-M] Temporary moving 'tfm_spm_hal_configure_default_isolation' out of FIH mointoring

Hi,

We are refining the HAL logics for MMIO, so this legacy API 'tfm_spm_hal_configure_default_isolation', which is now monitored under FIH library would be out of monitoring for a while.

The successors for this API would be added back after the refining is done, unless there are coming FIH updates.

Moving this single function out of FIH monitoring won't trigger problems - in most of the cases this API just returns without actions as few partition has bound MMIOs.

Thanks.
