openpower: move to new FSI external mode API
The kernel now supports an external mode switch for use with eg. a FSP
debug box.
This switch can be used by the fsi-disable to relinquish control of the
FSI pins in a fsi-master-gpio device, which also sets the mux and other
pins to the appropriate state.
When disabling external mode a rescan is triggered, so the fsi-enable
service does not need to explicitly do this.
