Subject: [PATCH 08/10] ravb: Add magic_pkt to struct ravb_hw_info

E-MAC on R-Car supports magic packet detection, whereas RZ/G2L
does not support this feature. Add magic_pkt to struct ravb_hw_info
and enable this feature only for R-Car.

RFC->v1:
 * Removed the feature checking from interrupt handler.
