armv8: ls1028a: disable multimedia for ls1027a, ls1017a

Browse Source 
ls1028a has 4 personalities: ls1028a, ls1027a, ls1017a and ls1018a.
Both ls1027a and ls1017a personalities are lower functionality version
which doesn't support the multimedia subsystems, like LCD, GPU.

To disable multimedia feature on non-multimedia version,
set the status property to disabled in dts nodes.
