net: stmmac: socfpga: remove phy_resume() call



As the previous commit addressed DWGMAC resuming with a PHY in
suspended state, there is now no need for socfpga to work around
this. Remove this code.

	/* Before the enet controller is suspended, the phy is suspended.
	 * This causes the phy clock to be gated. The enet controller is
	 * resumed before the phy, so the clock is still gated "off" when
	 * the enet controller is resumed. This code makes sure the phy
	 * is "resumed" before reinitializing the enet controller since
	 * the enet controller depends on an active phy clock to complete
	 * a DMA reset. A DMA reset will "time out" if executed
	 * with no phy clock input on the Synopsys enet controller.
	 * Verified through Synopsys Case #8000711656.
	 *
	 * Note that the phy clock is also gated when the phy is isolated.
	 * Phy "suspend" and "isolate" controls are located in phy basic
	 * control register 0, and can be modified by the phy driver
	 * framework.
