ACPI: VIOT: Initialize the correct IOMMU fwspec
[ Upstream commit 47d26684185d09e083669bbbd0c465ab3493a51f ]
When setting up DMA for a PCI device, we need to initialize its
iommu_fwspec with all possible alias RIDs (such as PCI bridges). To do
this we use pci_for_each_dma_alias() which calls
viot_pci_dev_iommu_init(). This function incorrectly initializes the
fwspec of the bridge instead of the device being configured. Fix it by
passing the original device as context to pci_for_each_dma_alias().
