x86: remove support for the Rise CPU
The Rise CPUs were only very short-lived, and there are no reports of anyone both owning one and running Linux on it. Googling for the printk string "CPU: Rise iDragon" didn't find any dmesg available online. If it turns out that against all expectations there are actually users reverting this patch would be easy. This patch will make the kernel images smaller by a few bytes for all i386 users.
