[U-Boot] [PATCH v2 02/11] usb: Generic USB Kconfig option, that fits both host and gadget and comments

[Paul Kocialkowski]

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.
