[PATCH] [RESEND] usb/gadget: aspeed-vhub: add USB_LIBCOMPOSITE dependency

Without that option, we run into a link failure:

drivers/usb/gadget/udc/aspeed-vhub/hub.o: In function `ast_vhub_std_hub_request':
hub.c:(.text+0x5b0): undefined reference to `usb_gadget_get_string'

Fixes: 7ecca2a4080c ("usb/gadget: Add driver for Aspeed SoC virtual hub")

Greg, as discussed in https://patchwork.kernel.org/patch/10427921/,
please apply this as a bugfix for 4.18.

Which I acked too though on second thoughts, shouldn't the driver
select USB_LIBCOMPOSITE ? No biggie, either way and that patch
can/should go in, we can change things later if we change our mind.

Cheers,
