usb/gadget: Kconfig: fix separate building of configfs-enabled functions 



USB_CONFGFS_ZZZZ should appear under a tristate option in order to allow
selecting more than one function without building the legacy gadgets.
Now there are two problems:

1) they can't be selected at all, because they depend on USB_CONFIGFS,
and the patch which adds USB_CONFIGFS has not been merged.
2) they don't select USB_LIBCOMPOSITE (which they need but which is
selected by USB_CONFIGFS)

config USB_CONFIGFS

	tristate "USB functions configurable through configfs"

	select USB_LIBCOMPOSITE

	help

	  A Linux USB "gadget" can be set up through configfs.

	  If this is the case, the USB functions (which from the host's

	  perspective are seen as interfaces) and configurations are

	  specified simply by creating appropriate directories in configfs.

	  Associating functions with configurations is done by creating

	  appropriate symbolic links.

	  For more information see Documentation/usb/gadget-configfs.txt.



config USB_CONFIGFS_SERIAL

	boolean "Generic serial bulk in/out"

	depends on USB_CONFIGFS

	depends on TTY

	select USB_U_SERIAL

	select USB_F_SERIAL

	help

	  The function talks to the Linux-USB generic serial driver.



config USB_CONFIGFS_ACM

	boolean "Abstract Control Model (CDC ACM)"

	depends on USB_CONFIGFS

	depends on TTY

	select USB_U_SERIAL

	select USB_F_ACM

	help

	  ACM serial link.  This function can be used to interoperate with

	  MS-Windows hosts or with the Linux-USB "cdc-acm" driver.



config USB_CONFIGFS_OBEX

	boolean "Object Exchange Model (CDC OBEX)"

	depends on USB_CONFIGFS

	depends on TTY

	select USB_U_SERIAL

	select USB_F_OBEX

	help

	  You will need a user space OBEX server talking to /dev/ttyGS*,

	  since the kernel itself doesn't implement the OBEX protocol.



config USB_CONFIGFS_NCM

	boolean "Network Control Model (CDC NCM)"

	depends on USB_CONFIGFS

	depends on NET

	select USB_U_ETHER

	select USB_F_NCM

	help

	  NCM is an advanced protocol for Ethernet encapsulation, allows

	  grouping of several ethernet frames into one USB transfer and

	  different alignment possibilities.



config USB_CONFIGFS_ECM

	boolean "Ethernet Control Model (CDC ECM)"

	depends on USB_CONFIGFS

	depends on NET

	select USB_U_ETHER

	select USB_F_ECM

	help

	  The "Communication Device Class" (CDC) Ethernet Control Model.

	  That protocol is often avoided with pure Ethernet adapters, in

	  favor of simpler vendor-specific hardware, but is widely

	  supported by firmware for smart network devices.



config USB_CONFIGFS_ECM_SUBSET

	boolean "Ethernet Control Model (CDC ECM) subset"

	depends on USB_CONFIGFS
