[PATCH net-next v2 13/15] net: mvpp2: reset the MACs when reconfiguring a port

[Antoine Tenart]

This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset
while a port is reconfigured. This is done so that we make sure a MAC is
in a reset state when not used, as only one of the two will be set out
of reset after the port is configured properly.
