Prarit Bhargava 6ecdea91ef tools/power turbostat: Fix /dev/cpu_dma_latency warnings ...

[ Upstream commit 40aafc7d58 ]

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.
