Subject: [PATCH net-next 3/5] net: stmmac: intel: remove unnecessary field
 struct plat_stmmacenet_data::ext_snapshot_num

Do not store bitmask for enabling AUX_SNAPSHOT0. The previous commit
("net: stmmac: fix PPS capture input index") takes care of calculating
the proper bit mask from the request data's extts.index field, which is
0 if not explicitly specified otherwise.
