Recognize AML Meson8 baby platform - S805 chip

Recognize Amlogic S805 chip, will need it for deciding if we should play h265 or not (S805 supports it, S802 doesn't). I don't have any S805 board here at the moment so will not make any changes to AMLCodec. Will get one within week or two then I can test and PR AMLCodec changes.
I taught of it before making PR, but figured why to change order in which chipsets became available? Beside, there should be written another code in future for this function because I found in kernel sources that some newer boards will represent itself as S802 (Meson8), but difference will be in cpu id. Need to investigate that more.
