Power Supply Cold Redundancy

[Yang, Cheng C]

Originally, I also thought I may push my code to phosphor-power, but 
when I was trying to devtool modify phosphor-power, I found a error happen

ERROR: Nothing PROVIDES 'openpower-dbus-interfaces' (but 
/home/cyang29/openbmc-openbmc/meta-phosphor/recipes-phosphor/power/phosphor-power_git.bb 
DEPENDS on or otherwise requires it).

We do not use openpower-dbus-interfaces.
