drm/msm: switch msm_kms_init_aspace() to use device_iommu_mapped()

Browse source

Change msm_kms_init_aspace() to use generic function
device_iommu_mapped() instead of the fwnode-specific interface
dev_iommu_fwspec_get(). While we are at it, stop referencing
platform_bus_type directly and use the bus of the IOMMU device.
