Fix broken verify functionality in crc32 command

"Roll crc32 into hash infrastructure"

The crc32 command with no -v expects an optional 3rd argument to be an
address to store the result in. With the -v switch, the last argument
is a crc, not an address. In the case where -v is set, we should set the
HASH_FLAG_ENV flag since that will first look for the value to be a
digest value, which matches the expected API for the crc32 command.

dm: usb: Fix finding of first upstream usb-2 hub in the ehci dm code

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.

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
