arm: dts: ls2080aqds: add CONFIG_MULTI_DTB_FIT support

Add support for selecting the appropriate DTS file depending on the
SERDES protocol used.

The fsl-ls2080a-qds DTS will be used by default if there isn't a DTS
file specifically made for the current SERDES protocol.

This patch adds the necessary DPMAC nodes (DPMAC 1-8) for
protocol 42 (0x2A) on SD#1.

Also, in case CONFIG_DM_ETH and CONFIG_MULTI_DTB_FIT are enabled
implement the board_fit_config_name_match() function in order to choose
the appropriate DTS.
