That'll avoid potential problems with CPU renumbering, and prevent the kernel from complaining at boot time. Otherwise, this looks fine. Thanks, Mark.

This patch modifies the device tree for tegra124 based devices to enable the Cortex A15 PMU. The interrupt numbers are taken from NVIDIA TRM DP-06905-001_v03p. This patch was tested on a Jetson TK1.
