Subject: [PATCH net-next v4 09/12] net: dsa: lantiq_gswip: add vendor
 property to setup MII refclk output

Read boolean Device Tree property "maxlinear,rmii-refclk-out" and switch
the RMII reference clock to be a clock output rather than an input if it
is set.

v4: set GSWIP_MII_CFG_RMII_CLK bit in RMII case inside the switch
    statement instead of a (wrong) if-clause just below
