[PATCH v2 gnumach] smp: Remove hardcoded AP_BOOT_ADDR

This took some time to figure out. Involves a hand-crafted 16 bit assembly instruction [1] because it requires an immediate for the memory address of far jump. This required self-modifying code to inject the next instruction, therefore I added a near jump to clear the instruction cache queue in ca
