USB requests should be processed within a timeframe of 5s.
The linux kernel also uses this timeout value for the control packets.
For the musb the increase in timeout helps successfully probing USB devices
(at least on one test hardware), but on the other hand doesn't slow down the
system, if there are no devices, i.e. the timeout never hits. That means,
that the USB core correctly aborts instead of timing out.
Why and how the 100ms was chosen in the first place, can not be deduced from
the git history, just that it seems to work fine for most boards.
Change USB_CNTL_TIMEOUT to 5000ms and replace all occurences of
`USB_CNTL_TIMEOUT * x`
with just
`USB_CNTL_TIMEOUT`,
as the timeout is now large enough without it.

This introduces the device parameters:
usbgadget.product
usbgadget.vendor
usbgadget.manufacturer
usbgadget.productname
These variables are used to configure the USB vendor id, product id,
manufacturer name and product name.
Previously these were configured with arguments to the usbserial
and dfu command. The parameters are device static, so it's nice to
configure it somewhere in the environment instead of when calling
dfu/usbserial. Also when other gadget drivers are added we do not
have to duplicate the option parsing further.

Currently we have two conflicting definitions of struct usb_config_descriptor
and struct usb_interface_descriptor in the tree. This is because the USB code
uses additional fields in the structs for internal housekeeping. Add
struct usb_interface and struct struct usb_configuration with the housekeeping
data and embed the corresponding hardware structs into them. This frees the
way to use the definitions from ch9.h in the next step.
