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.
Ok, I'll change it that way. Related to your code, I'd say it makes wrong assumption... MXS and MXL chips are designed for MIDs, while MX is designed for STB (same as difference between S802 and M802 eg.). More accurate would be to check if PMU driver nodes exists. Way you check now it assumes that ethernet device is not present. What if you hook up usb ethernet adapter to tablet or usb stick?
