[U-Boot] [v3 1/2] armv8: ls1043a/ls2080a: check SoC by device ID
Check LS1043A/LS2080a by device ID without using personality ID to determine revision number. This check applies to all various personalities of the same SoC family.
Signed-off-by: Wenbin Song wenbin.song@nxp.com --- Changes for v2: Modify the commit message and subject.
