USB: dwc3-msm: Turn ON clocks before bringing PHYs out of suspend in resume

On some platforms, USB3 controller sits on PCNOC. For those targets, needs
to turn ON iface_clk before accessing PHY registers while bringing PHYs
out of suspend.  Otherwise PHY register access fails during suspend exit.
Hence move enabling clocks before bringing PHYs out of suspend to fix it.
