[PATCH net-next 3/3] net: stmmac: leave enabling _RE and _TE to stmmac_mac_link_up()

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

We only need to enable the MAC receiver and transmiter only when the
link has come up.

With commit "net: stmmac: move phylink_resume() after resume setup
is complete" we move the race between stmmac_mac_link_up() and
stmmac_hw_setup(), ensuring that stmmac_mac_link_up() happens
afterwards. This patch is a pre-requisit of this change.

Remove the unnecessary call to stmmac_mac_set(, true) in
stmmac_hw_setup().
