Subject: [PATCH] ARM: tegra: use IO_ADDRESS for getting virtual address

Use macro IO_ADDRESS for getting virtual address of
corresponding physical address to make the consistency
with rest of Tegra code-base.
This macro calls the IO_TO_VIRT() which is defined in
arch/arm/mach-tegra/include/mach/iomap.h
