usb: gadget: select CONFIG_CRC32

Browse Source 
Without crc32 support, this driver fails to link:

arm-linux-gnueabi-ld: drivers/usb/gadget/function/f_eem.o: in function `eem_unwrap':
f_eem.c:(.text+0x11cc): undefined reference to `crc32_le'
arm-linux-gnueabi-ld: drivers/usb/gadget/function/f_ncm.o:f_ncm.c:(.text+0x1e40):
more undefined references to `crc32_le' follow
