When a driver doesn't know how much data a device is going to send,
the buffer size should be at least as big as the endpoint's maxpacket
value.  The serial drivers don't follow this rule; many of them
request only 256-byte bulk-in buffers.  As a result, they suffer
overflow errors if a high-speed device wants to send a lot of data,
because high-speed bulk endpoints are required to have a maxpacket
size of 512.

This patch (as1450) fixes the problem by using the driver's
bulk_in_size value as a minimum, always allocating buffers no smaller
than the endpoint's maxpacket size.

The USB stack historically has conflated device numbers (i.e., the
value of udev->devnum) with device addresses.  This is understandable,
because until recently the two values were always the same.

But with USB-3.0 they aren't the same, so we should start calling
these things by their correct names.  This patch (as1449b) changes many
of the references to "address" in the hub driver to "device number"
or "devnum".

The patch also removes some unnecessary or misleading comments.

register. As a result we'll fail to detect the plug event. Check the port

OMAP4430 is embedded with UTMI PHY. This PHY does not support the
OTG features like ID pin detection and VBUS detection. This function
is exported to an external companion chip TWL6030. Software must retrieve
the OTG HNP and SRP status from the TWL6030 and configure the bits inside
the control module that drive the related USBOTGHS UTMI interface signals.
It must also read back the UTMI signals needed to configure the TWL6030
OTG module.

Can find more details in the TRM[1].

Just a few cosmetic fixes to usb_gadget_probe_driver()
and usb_gadget_unregister_driver().

Decreased a few indentation levels with goto statements.

While at that, also add the missing call to musb_stop().
If we don't have OTG, there's no point of leaving
MUSB prepared for operation if a gadget driver fails
to probe. The same is valid for usb_gadget_unregister_driver(),
since we are removing the gadget driver and we don't have
OTG, we can completely unconfigure MUSB.
