Initialize the secure register bank (SMMU_SEC_SID_S) with sane default
values during the SMMU's reset sequence.
This change ensures that key fields, such as the secure ID registers,
GBPA reset value, and queue entry sizes, are set to a known-good state.
The SECURE_IMPL attribute of the S_IDR1 register will be introduced
later via device properties.
This is a necessary step to prevent undefined behavior when secure SMMU
features are subsequently enabled and used by software.
