net: mscc: ocelot: drop workaround for forcing RX flow control
As phylink gained generic support for PHYs with rate matching via PAUSE
frames, the phylink_mac_link_up() method will be called with the maximum
speed and with rx_pause=true if rate matching is in use. This means that
setups with 2500base-x as the SERDES protocol between the MAC/PCS and
the PHY now work with no need for the driver to do anything special.
Tested with fsl-ls1028a-qds-7777.dts.
