Revert "ARM: dts: msm: Enable notification LED on liquid8994"

This reverts commit 6a959d1c.

The reverted commit provided a temporary solution for turning on a LED
while the liquid is booting in order to get indication that the device
is “alive”. A LED is turned-on in the LED probe function and tuned-
off after 5 seconds. In the new solution the LED will be
turned-on in bootloader, and will be turned off before the launcher
shows up.
