Revert "ARM: dts: msm: add shutdown voltage for Waipio platforms"

Browse Source 
This reverts commit 7e0e6abe01.

With the commit being reverted, kernel_power_off() would be invoked
whenever the battery SOC reaches 0, battery is discharging and
the battery voltage goes below the specified shutdown voltage. This
was made to avoid an UVLO reset if the shutdown initiated by the
userspace takes longer than expected time. However, in certain
conditions, when filesystem sync didn't go as expected and with UFS
or storage drivers removing the devices in their shutdown callbacks,
init process is getting a SIGBUS exit code ending up in a kernel
panic. With recent testing, it is also found out that an UVLO reset
is not happening as before even though the shutdown still takes
longer than expected. Taking this into consideration, reverting
the change seems fine.
