tools/power turbostat: Fix /dev/cpu_dma_latency warnings
When running as non-root the following error is seen in turbostat:
turbostat: fopen /dev/cpu_dma_latency
: Permission denied
turbostat and the man page have information on how to avoid other
permission errors, so these can be fixed the same way.
Provide better /dev/cpu_dma_latency warnings that provide instructions on
how to avoid the error, and update the man page.
