[PATCH] Revert "mfd: tps65910: Convert ti, system-power-controller DT property to poweroff-source"

[johan@kernel.org (Johan Hovold)]

This reverts commit 25f833c1171d ("mfd: tps65910: Convert
ti,system-power-controller DT property to poweroff-source"), which
switched to a new device-tree property name for configuring the device
as a power-off controller, but failed to update the affected device-tree
sources and neither provided backward compatibility with the old
property name.

This fixes broken power-off functionality for all boards relying on
tps65910 to power off the system.
