arm64: Provide a namespace to NCAPS
commit 06f9eb884be81431d54d7d37390043e3b5b7f14a upstream
Building arm64.allmodconfig leads to the following warning:
usb/gadget/function/f_ncm.c:203:0: warning: "NCAPS" redefined
#define NCAPS (USB_CDC_NCM_NCAP_ETH_FILTER | USB_CDC_NCM_NCAP_CRC_MODE)

#define NCAPS 2
So add a ARM64 prefix to avoid such problem.
