Add support for AMD Ryzen flashing

Tested AMD Ryzen Support on HP Pavilion 590-p0077c, I am able to flash
using F.15 or older, but I can downgrade if a newer Firmware is
installed using afuwinx64 which is a 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 comes with a AMD Ryzen 3 2200G with
16MB, so it may not work with chips more that 16MB, it is currently
untested by me, since this is the only AMD PC I own.
