AMD NAVI23 update

The main reason to provide an update here is having Linux AMD driver support on Macs with modern AMD NAVI23 graphics cards and getting amdvbflash support to read video BIOS card. Writing fails because the upgraded external version of amdvbflash does not allow to force a write. Recently I got hold of an RX6600M 8GB MXM card - which offers new obstacles to overcome.
