sfc: Rename efx_board::init_leds to init_phy and use for SFN4111T
efx_board::init_leds was introduced as a second stage of
initialisation because of the inter-dependency between the board and
PHY. We want to move board initialisation into NIC probing, which is
too early to use MDIO, so SFN4111T initialisation also needs to be
split.
