Move CONFIG_USB_GADGET_DUALSPEED option to Kconfig and
make all UDC controllers select USB_GADGET_DUALSPEED:
  - add next options to Kconfig selecting USB_GADGET_DUALSPEED:
    - USB_GADGET_ATMEL_USBA
    - USB_GADGET_DWC2_OTG
    - USB_DWC3
    - CI_UDC
  - make USB_MUSB_GADGET select USB_GADGET_DUALSPEED

While at it, make some related fixes:
  - remove DUALSPEED from configs that don't enable gadget support:
    - kwb.h
    - tseries.h
  - add missing USB_GADGET option to next configs:
    - novena_defconfig
    - pcm051_rev*_defconfig
    - xfi3_defconfig

The description was borrowed from kernel. "tristate" type was changed
to "bool" (I believe we don't support modules for u-boot yet, right?).
CONFIG_USB_GADGET requires CONFIG_USB to be defined too, so add it along
as well.

Definitions were added to defconfig files in a way that
"make savedefconfig" generates exactly the same file as used defconfig.

Having MUSB_HOST and MUSB_GADGET in Kconfig allows more flexibility with regard
to what Kconfig options to enable, such as USB_STORAGE or USB_KEYBOARD.

There is no particular reason why the USB Kconfig option should be specific to
host mode. In prevision of adding MUSB host and gadget to Kconfig, this moves
the title and help message of the USB Kconfig option to a more generic format.

Adding comments to the usb Kconfig allows for a better separation and more
readability in generated configs and in menuconfig.

The USB_ARCH_HAS_HCD currently serves no purpose and adds some confusion to the
required Kconfig options that are required to have USB support.

Dropping it makes things easier and doesn't break anything, since it was unused
anyways.

With recent additions to USB Kconfig the number of USB options had grown
large enough to warrant a separate menu for USB.

Add a Kconfig menu for USB.

In Linux USB_DEVICE() is used to declare a USB device by vendor/device ID.
We should follow the same convention in U-Boot. Rename the existing
USB_DEVICE() macro to U_BOOT_USB_DEVICE() and bring in the USB_DEVICE()
macro from Linux for use in U-Boot.
