ACPI: DPTF: Add support for high frequency impedance notification
Add high frequency impedance notification support under DPTF.
This returns high frequency impedance value that can be obtained
from battery fuel gauge whenever there is change over a threshold.
Also, corrected the typo from IMPEDANCED_CHNGED to IMPEDANCE_CHANGED.
