[ Upstream commit 19eb465c969f3d6ed1b98506d3e470e863b41e16 ]
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.
Fixes: b812834b53 ("iommu: arm-smmu-qcom: Add sdm630/msm8998 compatibles for qcom quirks")
