regulator: pfuze: provide power over standby handler
This patch is providing an optional power off handler
which will configure standby state of the PMIC to disable all power lines.

In my power consumption test on RIoTBoard, I got the following results:
power off without this patch:   320 mA
power off with this patch:      2   mA
