Use the generic PHY framework API to get the PHY. The usb_phy_set_resume
and usb_phy_set_suspend is replaced with power_on/get_sync and
power_off/put_sync to align with the new PHY framework.
musb->xceiv can't be removed as of now because musb core uses xceiv.state and
xceiv.otg. Once there is a separate state machine to handle otg, these can be
moved out of xceiv and then we can start using the generic PHY framework.

see, weird unbalanced calls :-)
Make it all explicit:
phy_pm_runtime_get_sync(phy);
phy_init(phy);
phy_pm_runtime_put(phy);
I think then it makes sense to drop get_sync from phy_init()?
Thanks
