usb.h: Always declare usb function prototypes

There is no harm in declaring the function prototypes even if nothing
implements them, and when CONFIG_DM_USB=y the various usb functions are
available regardless of any controller drivers being enabled.

This fixes compile warnings due to missing prototypes on ARCHs where
the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers.

One could argue that in the case of no controllers CONFIG_DM_USB should not
be set, but this problem is typically seen during bringup of boards which
do actually have usb controllers.

dm: usb: Add support for companion controllers

USB companion controllers must be scanned after the main controller has
been scanned, so that any devices which the main controller which to hand
over to the companion have actually been handed over before we scan the
companion.

As there are no guarantees that this will magically happen in the right
order, split the scanning of the buses in 2 phases, first main controllers,
and then companion controllers.

Interrupt endpoints typically are polled for a long time by the usb

take a long time to complete this.

To avoid this the u-boot code has the an interrupt queue mechanism / API,
add support for this to the driver-model usb code and implement it for the
dm ehci code.

dm: usb: Copy over usb_device values from usb_scan_device() to final usb_device

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.
