Added missing __iomem annotation in order to fix the following
sparse warnings:

drivers/pci/host/pci-tegra.c:411:41: warning: incorrect type in return expression (different address spaces)
drivers/pci/host/pci-tegra.c:411:41:    expected void [noderef] <asn:2>*
drivers/pci/host/pci-tegra.c:411:41:    got void *addr
drivers/pci/host/pci-tegra.c:419:25: warning: incorrect type in return expression (different address spaces)
drivers/pci/host/pci-tegra.c:419:25:    expected void [noderef] <asn:2>*
drivers/pci/host/pci-tegra.c:419:25:    got void *addr
