[PATCH net] net: dsa: microchip: Save the periodic output flags and index

["Bastien Curutchet (Schneider Electric)" <bastien.curutchet@bootlin.com>]

When the periodic output is restarted, the request flags and index are
always set to 0. So if a pin other than the first one was used, or if a
flag was set in the request that triggered the periodic output, it is
lost when the output is restarted.

Save the request's flags and index when the periodic output is
initialized.
Use the save flags and index when the periodic output is reset
