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

Browse Source 
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
