Prarit Bhargava 5ea7647b33 tools/power turbostat: Warn on bad ACPI LPIT data
On some systems /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
or /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
return a file error because of bad ACPI LPIT data from a misconfigured BIOS.
turbostat interprets this failure as a fatal error and outputs

	turbostat: CPU LPI: No data available

If the ACPI LPIT sysfs files return an error output a warning instead of
a fatal error, disable the ACPI LPIT evaluation code, and continue.
