ARM: tegra: Use readl/writel_relaxed for reset

tegra_assert_system_reset is called after the cache is disabled.
Calling writel will cause the PL310 store buffers to be drained,
which requires taking a spinlock.  Taking a spinlock is not safe
after the caches are disabled.  Convert to readl_relaxed and
writel_relaxed.
