x86, apic: Introduce the NOOP apic driver
Introduce NOOP APIC driver. We should use it in case if apic was
disabled due to hardware of software/firmware problems (including
user requested to disable it case).
The driver is attempting to catch any inappropriate apic operation
call with warning issue.
Also it is possible to use some apic operation like IPI calls,
read/write without checking for apic presence which should make
callers code easier.
