Commit 4dfb80d18d05 ("net: fec: cache statistics while device is down")
introduced unconditional statistics-related actions.
However, when driver is compiled with CONFIG_M5272, staticsics-related
definitions do not exist, which results into build errors.
Fix that by adding explicit handling of !defined(CONFIG_M5272) case.

Changes since v1:
- instead of #ifdef'ing calls to fec_enet_update_ethtool_stats(), add
definition of empty fec_enet_update_ethtool_stats() for CONFIG_M5272
case,
- add FEC_STATS_SIZE macro to avoid #ifdef in the middle of
alloc_etherdev_mqs() args.
