The controller will reset and run into error state if turn
off power when suspend in host mode. This patch stop hcd to
make the controller into L3 state to make sure that the
controller and driver state will reset when resume.

The commit dc71e51944 ("usb: dwc2: make otg manage lowlevel
hw on its own") aimed to control the clk and phy power for
otg mode, but it also introduced lost of new problems, so we
revert it.
This patch only controls phy power for otg mode, it can fix
the dwc2 udc start fail issue with the following error log:
dwc2_hsotg_init_fifo: timeout flushing fifos (GRSTCTL=80000430)
dwc2_core_reset() HANG! Soft Reset GRSTCTL=80000001

When handle disconnect of the hcd during bus_suspend, hcd
needs to resume its root hub, otherwise the root hub will
not disconnect the existing devices under its port.
This issue always happens when connecting with usb devices
which support auto-suspend function (e.g. usb hub).

Originally, dwc2 just handle one clock named otg, however, it may have
two or more clock need to manage for some new SoCs, so this adds
change clk to clk's array of dwc2_hsotg to handle more clocks operation.

On the rk3288 USB host-only port (the one that's not the OTG-enabled
port) the PHY can get into a bad state when a wakeup is asserted (not
just a wakeup from full system suspend but also a wakeup from
autosuspend).
We can get the PHY out of its bad state by asserting its "port reset",
but unfortunately that seems to assert a reset onto the USB bus so it
could confuse things if we don't actually deenumerate / reenumerate the
device.
We can also get the PHY out of its bad state by fully resetting it using
the reset from the CRU (clock reset unit) in chip, which does a more full
reset. The CRU-based reset appears to actually cause devices on the bus
to be removed and reinserted, which fixes the problem (albeit in a hacky
way).
It's unfortunate that we need to do a full re-enumeration of devices at
wakeup time, but this is better than alternative of letting the bus get
wedged.

On some platform, external MSI domain is using instead of the one
created by designware driver. For instance, if using GIC-V3-ITS
as a MSI domain, we only need set msi-map in the devicetree but
never need any bit in the designware driver to handle MSI stuff.
So skip allocating its own MSI domain for that case.
