Add support for basic power management on

It can work only till retention or it can work with off-mode too with
this series? Form what I could make out, it'll work till retention.
right?
this is not runtime PM and I haven't tested with OMAP. All in all, it
should work with both, but only testing will tell. Maybe we _do_ need to
restart the whole IP in that case. At least with PCIe FPGA, it survived
just fine a suspend-to-ram (echo mem > /sys/power/state).
I'll see if I can test suspend-to-disk later today or tomorrow.
Ok. Just one thing. I don't see three registers getting restored
properly (needed when suspend-to-disk). One is DWC3_GCTL, which is being
initialized in dwc3_core_init and the other is DWC3_DCFG and DWC3_DCTL
initialized in dwc3_gadget_init().
