It is trivial to relax the restriction and permit read/write access.

are passed verbatim to dma_buf calls.

any functionality.

This patch removes this limitation. With this patch it is possible

1) Multiple gadgets build in
2) Part of functions build in, part of functions as a modules
3) Some gadgets build in and some part of functions build in/modules
etc.

As this patch makes Kconfig quite complicated let me clarify how it works:

USB_F_<func name> - used in makefile for compilation
USB_CONFIGFS_F_<func name> - Chosen by user in function menu
USB_G_<gadget name>_REQ_F_<func name> - set up by gadget to mark
      that this particular gadget requires this func to work
USB_F_<func name>_SELECTOR - helper config which is used to determine
    if function should be build in or compiled as a module

The rules are quite simple:
1) If any of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, then USB_F_<func name> is set to y and function is build in
2) If none of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, but any of them equals m then USB_F_<func name> is set to m and function
