iommu/arm: fix ARM_SMMU_QCOM compilation
My previous bugfix ended up making things worse for the QCOM IOMMU
driver when it forgot to add the Kconfig symbol that is getting used to
control the compilation of the SMMU implementation specific code
for Qualcomm.
Fixes: 424953cf3c66 ("qcom_scm: hide Kconfig symbol")
