This adds a weak definition of board_update_comphy_map to comphy_core, which does nothing. If this function is defined elsewhere, for example in board file, the board file can change some parameters of SERDES configuration.
This is needed on Turris Mox, where the SERDES speed on lane 1 has to be set differently when SFP module is connected and when Topaz Switch module is connected.
This is a temporary solution. When the comphy driver for armada-3720 will be added to the kernel, the comphy driver in u-boot shall also be updated and this should be done differently then.
