[ Upstream commit 3b6a18f0da8720d612d8a682ea5c55870da068e0 ]
Compile-testing IMX_MU_MSI on x86 without PCI_MSI support results in a build failure:
drivers/gpio/gpio-sprd.c:8: include/linux/gpio/driver.h:41:33: error: field 'msiinfo' has incomplete type drivers/iommu/iommufd/viommu.c:4: include/linux/msi.h:528:33: error: field 'alloc_info' has incomplete type
Tighten the dependency further to only allow compile testing on Arm. This could be refined further to allow certain x86 configs.
This was submitted before to address a different build failure, which was fixed differently, but the problem has now returned in a different form.
