Subject: [net-next 13/21] can: at91_can: silence clang warning

This patch fixes the following clang warning, by marking the functions
as maybe unused. gcc doesn't complain about unused inline functions.

| drivers/net/can/at91_can.c:178:1: warning: unused function 'at91_is_sam9X5' [-Wunused-function]
| AT91_IS(9X5);
| ^
| drivers/net/can/at91_can.c:172:19: note: expanded from macro 'AT91_IS'
| static inline int at91_is_sam##_model(const struct at91_priv *priv) \
|                   ^
| <scratch space>:66:1: note: expanded from here
| at91_is_sam9X5
| ^
