[PATCH net-next 3/3] net: stmmac: sti: convert to stmmac_pltfr_pm_ops

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

As we now have the plat_dat->init()/plat_dat->exit() populated which
have the required functionality on suspend/resume, we can now use
stmmac_pltfr_pm_ops which has methods that call these two functions.
Switch over to use this.

Doing so also fills in the runtime PM ops and _noirq variants as well.
