Subject: [PATCH 3/3] iommu: qcom: Drop of_match_ptr to fix -Wunused-const-variable

The of_device_id is included unconditionally by of.h header and used
in the driver as well.  Remove of_match_ptr to fix W=1 compile test
warning with !CONFIG_OF:

    drivers/iommu/qcom_iommu.c:910:34: warning: 'qcom_iommu_of_match' defined but not used [-Wunused-const-variable=]
      910 | static const struct of_device_id qcom_iommu_of_match[] = {
