sfc: SFT9001/SFN4111T: Check PHY boot status during board initialisation
During SFN4111T initialisation, check whether the PHY boot status
indicates a bad firmware checksum. If so, prepare to reflash rather
than continuing with normal initialisation.
Remove redundant PHY boot status check from tenxpress_phy_init().
