ARM: tegra: call cpu_do_idle from C code
When building a kernel for multiple CPU architecture levels, cpu_do_idle() is a macro for an indirect function call, which cannot be called from assembly code as Tegra does. Adding a trivial C wrapper for this function lets us build a tegra kernel with ARMv6 support enabled.
