iommu/arm-smmu-qcom: hook up qcom_smmu_impl for ACPI boot

Browse source

The hookup with qcom_smmu_impl is required to do ACPI boot on SC8180X
based devices like Lenovo Flex 5G laptop and Microsoft Surface Pro X.
Define acpi_platform_list for these platforms and match them using
acpi_match_platform_list() call, and create qcom_smmu_impl accordingly.

(np == NULL) is used to check ACPI boot, because fwnode of SMMU device
is a static allocation and thus helpers like has_acpi_companion() don't
work here.
