iommu/vt-d: Fix debugfs register reads
Commit 6825d3ea ("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.
