When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.
Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.

USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.
Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.
This patch removes the powering off calls, fixing the undesirable power
bouncing.
Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

On an usb stop instead of leaving orphan usb devices behind simply remove
them.
The result of this commit is best seen in the output of "dm tree" after
plugging out an usb hub with 2 devices plugges in and plugging in a keyb.
instead, before this commit the output would be:
usb [ + ] `-- sunxi-musb
usb_hub [ ] |-- usb_hub
usb_mass_st [ ] | |-- usb_mass_storage
usb_dev_gen [ ] | `-- generic_bus_0_dev_3
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
Notice the non active usb_hub child and its 2 non active children. The
first child being non-active as in this example also causes usb_get_dev_index
to return NULL when probing the first child, which results in the usb kbd
code not binding to the keyboard.
With this commit in place the output after swapping and "usb reset" is:
usb [ + ] `-- sunxi-musb
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
As expected, and usb_get_dev_index works properly and the keyboard works.

When submitting interrupt packets to an endpoint we only link in the ed

device, and a non interrupt endpoint 1 with another device we end up
with the same ed linked into both the periodic and async lists, which is
not good (tm).

The usb spec says that we must wait a minimum amount of time after port
power on (exact time is in the hub descriptor), this is something which
we must not only do for root ports but also for external hub ports, which
is why the common usb_hub code already waits a full second after powering
up ports. Having a separate wait for just the root hub in the ohci-hcd
code only leads to doing the waiting twice for the root ports, so drop the

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,

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
