riscv: make patch-function pointer more generic in cpu_manufacturer_info struct
During review the naming of the function-pointer was called confusing as the vendor id is just one of three inputs for the patching and indeed it serves no real purpose, as with recent changes the function pointer is not a static global element anymore, so drop the "vendor_" prefix.
