Use para_fill instead of directly setting the APIC ops to the result of the vmi_get_function call - this allows one to implement a VMI ROM without implementing APIC functions, just using the native APIC functions. While doing this, I realized that there is a lot more cleanup that should have been done. Basically, we should never assume that the ROM implements a specific set of functions, and always allow fallback to the native implementation. This is critical for future compatibility.
