Merge branch 'net-stmmac-sti-cleanups'

Russell King says:

====================
net: stmmac: sti cleanups

Clean up the STI platform glue code.

- IS_PHY_IF_MODE_RGMII() is just a duplicate for
  phy_interface_mode_is_rgmii(), so use the generic version that we
  already have.

- add init/exit functions that call clk_prepare_enable(),
  sti_dwmac_set_mode() and clk_disable_unprepare() as appropriate,
  converting to devm_stmmac_pltfr_probe().

- the custom suspend/resume ops do basically what the generic ones
  do with init/exit functions populated, but also add runtime and
  noirq ops. Update STI to use the generic ops.
