Add AMD Ryzen Support & VIA VL805 Support

Tested AMD Ryzen Support on HP Pavilion 590-p0077c, I am able to flash using F.15 or older, but can downgrade if newer FW is installed using afuwinx64 (vendor tool)
This is due to flashrom SPI lockdown on newer firmwares by HP. It seems HP UEFI Diags uses AFU Flash embedded in. It also came with a AMD Ryzen 3 2200G.
Also VL805 is working 100% for RPi4 USB XHCI FW Flashing, I had to change the RPi's chip (W25X10) to use rdid4 instead since it wouldn't work otherwise.
