Power down feature of DWC2 module integrated in Rockchip SoCs doesn't work
properly or needs some additional handling in PHY or SoC glue layer, so
disable it for now. Without disabling power down, DWC2 sporadically cannot
detect USB disconnect.

The dwc2 programming guide section 3.5 'Halting a Channel'
says that the application can disable any channel by
programming the HCCHARn register with the HCCHARn.ChDis
and HCCHARn.ChEna bits set to 1'b1. This enables the
dwc_otg host to flush the posted requests (if any) and
generates a Channel Halted interrupt.
But it also requires that channel disable must not be
programmed for non-split periodic channels. At the end
of the next uframe/frame (in the worst case), the core
generates a channel halted and disables the channel
automatically.
If we disable non-spilt periodic channels to halt the
channels, it will easily to cause data transfer fail.
A typical case is take photo with usb camera or close
usb camera, Specifically, the observed order is:
1. uvc driver calls usb_kill_urb
2. usb_kill_urb calls urb_dequeue to cancel urb
3. urb_dequeue call dwc_otg_hc_halt to disable
non-spilt periodic channels
4. usb core doesn't halt the non-spilt periodic
channels immediately, and the application
reallocates the channels for other transactions
without waiting for the HCINTn.ChHltd interrupt.
5. uvc driver calls usb_set_interface to start
control transfer, and gets a channel which used
for non-spilt periodic transfer before. The core
generates a channel halted and disables the channel
automatically. This cause control transfer fail.

The commit e6f2f6d63e ("usb: dwc2: power on/off phy for
otg mode") aimed to control phy power for otg mode, but
it also introduced a new problem, so we fix it.
This patch keep phy power on for otg if current mode is
host during dwc2 probe, otherwise the enumeration will
fail with the following error log:
Cannot enable. Maybe the USB cable is bad?
Cannot enable. Maybe the USB cable is bad?

When a usb device disconnects in a certain way, dwc2_queue_transaction
still gets called after dwc2_hcd_cleanup_channels.
dwc2_hcd_cleanup_channels does "channel->qh = NULL;" but
dwc2_queue_transaction still wants to dereference qh.
This adds a check for a null qh.

The operation mode of controller will change to peripheral when
resume if PD is power off during suspend, current code disconnect
hcd and set lx state to L3 in this case to make sure the controller
will be reinit in device mode, but that's not enough, the op_state
is still host which is change when init or ID change interrupt
occur. If the ID change happened after suspend the driver would
miss the interrupt, so when the application call the pullup function
to stop gadget and start again to change to another function, the
disconnect gadget operation can't be done and the gadget restart
directly. This will result in NULL point when gadget work. This
patch set op_state to OTG_STATE_B_PERIPHERAL when resume in this
case.

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.
