Subject: [PATCH 5.8 070/255] dmaengine: idxd: fix PCI_MSI build errors

[ Upstream commit d6a7bb869dd8a516901591136a9a895fd829d6c6 ]

Fix build errors when CONFIG_PCI_MSI is not enabled by making the
driver depend on PCI_MSI:

ld: drivers/dma/idxd/device.o: in function `idxd_mask_msix_vector':
device.c:(.text+0x26f): undefined reference to `pci_msi_mask_irq'
ld: drivers/dma/idxd/device.o: in function `idxd_unmask_msix_vector':
device.c:(.text+0x2af): undefined reference to `pci_msi_unmask_irq'
