This is a preparation patch for adding driver-model support.
Note we do keep ohci_dev as a separate struct so that we can later add
support for interrupt-queues which requires allocating a separate ohci_dev
per interrupt-queue.

The ehci driver model code for finding the first upstream usb-2 hub before
this commit has a number of issues:
1) "if (!ttdev->speed != USB_SPEED_HIGH)" does not work because the '!'
takes presedence over the '!=' this should simply be
"if (ttdev->speed == USB_SPEED_HIGH)"
2) It makes ttdev point to the first upstream usb-2 hub, but ttdev should
point to the last usb-1 device before the first usb-2 hub (when going
upstream from the device), as ttdev is used to find the port of the
first usb-2 hub to which the the last usb-1 device is connected.
3) parent_devnum however should be set to the devnum of the first usb-2
hub, so we need to keep pointers around to both usb_device structs.
To complicate things further during enumeration usb_device.dev will point
to the parent udevice, where as during normal use it will point to
the actual udevice, we must handle both cases correctly.
This commit fixes all this making usb-1 devices attached to usb-2 hubs,
including usb-1 devices attached to usb-1 hubs attached to usb-2 hubs, work.

Currently we copy over a number of usb_device values stored in the on stack
struct usb_device probed in usb_scan_device() to the final driver-model managed
struct usb_device in usb_child_pre_probe() through usb_device_platdata, and
then call usb_select_config() to fill in the rest.
There are 3 problems with this approach:
1) It does not fill in enough fields before calling usb_select_config(),
specifically it does not fill in ep0's maxpacketsize causing a div by zero
exception in the ehci driver.
2) It unnecessarily redoes a number of usb requests making usb probing slower
3) Calling usb_select_config() a second time fails on some usb-1 devices
plugged into usb-2 hubs, causing u-boot to not recognize these devices.
This commit fixes these issues by removing (*) the usb_select_config() call
from usb_child_pre_probe(), and instead of copying over things field by field
through usb_device_platdata, store a pointer to the in stack usb_device
(which is still valid when usb_child_pre_probe() gets called) and copy
over the entire struct.
*) Except for devices which are explictly instantiated through device-tree
rather then discovered through usb_scan_device() such as emulated usb devices
in the sandbox.

Make usb_get_bus easier to use for callers, by directly returning the bus
rather then returning it via a pass-by-ref argument.
This also removes the error checking from the current callers, as
we already have an assert() for bus not being NULL in usb_get_bus().

Add a delay of 1 microsecond before issuing soft reset to the

This prevents corruption of ULPI Function Control Register which

The 2/3 usb-phys on the sunxi SoCs are really a single separate functional
block, and are modelled as such in devicetree. So once we've moved all the
sunxi usb code to the driver-model then phy_probe will be called once
for the entire block from the driver-model enumeration code.
Move to this now as this also avoids problems with phy_probe being called
multiple times once we introduce ohci support. This also allows us to get rid
of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed
to be called only once.
Since we're effectively rewriting the probe / remove functions, move them
to the end of the file while we are at it, as that is the most logical place
for them.

The sunxi "usbc" code is mostly about phy setup, but currently also sets up
