Alan Tull d686ce4204 socfpga: hotplug: put cpu1 in wfi
Use WFI when putting CPU1 to sleep.  Don't hold CPU1 in reset
since that results in increased power consumption.

Reset CPU1 briefly during CPU1 bootup.

This has been tested for hotplug and suspend/resume and results
in no increased power consumption.
