ARM: 7118/1: rename temp variable in read*_relaxed() 

This resolves the following sparse warning from readl() and other macros,
which ends up embedding readl_relaxed() using the same variable.

arch/arm/mach-tegra/dma.c:169:8: warning: symbol '__v' shadows an earlier one
arch/arm/mach-tegra/dma.c:169:8: originally declared here
