USB: gadget: g_fs: code cleanup
This commit cleans the g_fs gadget hopefully making it more
readable. This is achieved by usage of the usb_string_ids_tab()
function for batch string IDs registration as well as
generalising configuration so that a single routine is
used to add each configuration and bind interfaces. As an
effect, the code is shorter and has fewer #ifdefs.
Moreover, in some circumstances previous code #defined
CONFIG_USB_FUNCTIONFS_GENERIC macro to prevent a situation
where gadget with no configurations is built. This code removes
the #define form source code and achieves the same effect using
select in Kconfig.
This patch also changes wording and names of the Kconfig options.
