Len Brown 09116eeea6 tools/power turbostat: Fix missing SYS_LPI counter on some Chromebooks
[ Upstream commit 1f81c5efc0 ]

Some Chromebook BIOS' do not export an ACPI LPIT, which is how
Linux finds the residency counter for CPU and SYSTEM low power states,
that is exports in /sys/devices/system/cpu/cpuidle/*residency_us

When these sysfs attributes are missing, check the debugfs attrubte
from the pmc_core driver, which accesses the same counter value.
