sfc: Implement message level control
Replace EFX_ERR() with netif_err(), EFX_INFO() with netif_info(), EFX_LOG() with netif_dbg() and EFX_TRACE() and EFX_REGDUMP() with netif_vdbg(). Replace EFX_ERR_RL(), EFX_INFO_RL() and EFX_LOG_RL() using explicit calls to net_ratelimit(). Implement the ethtool operations to get and set message level flags, and add a 'debug' module parameter for the initial value.
