Many USB host controller drivers contain almost identical copies of the
same virtual root hub descriptors. Put these into a common file to avoid
duplication.

Note that there were some very minor differences between the descriptors
in the various files, such as:

- USB 1.0 vs. USB 1.1
- Manufacturer/Device ID
- Max packet size
- String content

I assume these aren't relevant.

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

    USB: Fix complaints about strict aliasing in OHCI-HCD

tried to fix this, but gcc4.4 still complains. So, this
patch basically reverts the above and does a simpler fix.

also, the above commit incorrectly changed
	/* corresponds to data_buf[4-7] */
	datab [1] = 0;
to

	/* corresponds to databuf.u8[4-7] */
	databuf.u8[1] = 0;

Changed both to use a common timeout for URB submission, since they were using
different values and EHCI's was too short.

Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

The max packet size is encoded as 0,1,2,3 for 8,16,32,64 bytes.
At some places directly 8,16,32,64 was used instead of the encoded
value. Made a enum for the options to make this more clear and to help
preventing similar errors in the future.

After fixing this bug it became clear that another bug existed where
the 'pipe' is and-ed with PIPE_* flags, where it should have been
'usb_pipetype(pipe)', or even better usb_pipeint(pipe).

Also removed the triple 'get_device_descriptor' sequence, it has no use,
and Windows nor Linux behaves that way.
There is also a poll going on with a timeout when usb_control_msg() fails.
However, the poll is useless, because the flag will never be set on a error,
because there is no code that runs in a parallel that can set this flag.
Changed this to something more logical.

Tested on AT91SAM9261ek and compared the flow on the USB bus to what
Linux is doing. There is no difference anymore in the early initialisation
sequence.

A recent commit (936897d4)
enabled the usb_stop() command in common/cmd_bootm.c which was
not enabled for some time, because no board did actually set the
CFG_CMD_USB flag. So, now the usb_stop() is executed before
loading the linux kernel.

However, the usb_ohci driver hangs up (at least on AT91SAM) if the
driver is stopped twice (e.g. the peripheral clock is stopped on AT91).
If some other piece of code calls usb_stop() before the bootm command,
this command will hangup the system during boot.
(usb start and stop is typically used while booting from usb memory stick)

But, stopping the usb stack twice is useless anyway, and a flag already
existed that kept track on the usb_init()/usb_stop() calls.
So, we now check if the usb stack is really started before we stop it.

This problem is now fixed in both the upper as low-level layer.
