qemu: add x86 cpu
This patch adds a qemu x86 cpu chip. It has no initialization function as this isn't needed on virtual hardware. A virtual machine can have pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu -cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu which is (almost) identical to the one on the host machine. So I've added X86_VENDOR_ANY as wildcard match for the cpu_table.
