Subject: [PATCH 3.16.y-ckt 086/133] Input: ambakmi - fix system PM by converting to modern callbacks

3.16.7-ckt18 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ulf Hansson <ulf.hansson@...aro.org>

commit cee3d8ccbecb8af6788edaaac46befca78b000dc upstream.

The legacy system PM support has long time ago been dropped from the
AMBA bus. Align to that by converting to the modern system PM
callbacks.

Fixes: 26825cfd90f9 (ARM: 7914/1: amba: Drop legacy PM support ...)
