[ Upstream commit ba3b01d7a6 ]
Commit 6825d3ea6c ("iommu/vt-d: Add debugfs support to show register
contents") dumps the register contents for all IOMMU devices.
Currently, a 64 bit read(dmar_readq) is done for all the IOMMU registers,
even though some of the registers are 32 bits, which is incorrect.
Use the correct read function variant (dmar_readl/dmar_readq) while
reading the contents of 32/64 bit registers respectively.
