sfc: Change falcon_probe_board() to fail for unsupported boards
commit e41c11ee0cc602bcde68916be85fb97d1a484324 upstream. The driver needs specific PHY and board support code for each SFC4000 board; there is no point trying to continue if it is missing. Currently unsupported boards can trigger an 'oops'. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.
