So I gave this patch a try but it now blocks all deeper SoC idle
states as the PHY stays active. I think the real fix is to make
sure the charger behaves independent of the USB PHY state. So
probably this needs to be fixed in phy-twl4030-usb.c and
twl4030_charger.c instead. Now it sounds like we're also shutting
down the charger with the USB PHY.
