icnss: Add support for disabling vbatt notification

ICNSS monitors runtime phone power. When phone power
crosses either high or low threshold, ICNSS sends
vbatt notification to WLAN FW. FW then should vote for
different regulator power mode based on the notification.
Add support for disabling this feature and disable it
for now until WLAN FW support voting for different
regulator power mode.
