iommu/arm-smmu-qcom: apply num_context_bank fixes for SDM630 / SDM660

Browse source

The Qualcomm SDM630 / SDM660 platform requires the same kind of
workaround as MSM8998: some IOMMUs have context banks reserved by
firmware / TZ, touching those banks resets the board.

Apply the num_context_bank workaround to those two SMMU devices in order
to allow them to be used by Linux.
