* Move the legacy PIC and the IO-APIC code into their own source file. No

functional change intended.
* Use an appropriately sized sLevelTriggeredInterrupts for each controller type.
  This also fixes an out of bound access for IO-APICs with more than 32 entries
  and also returns the right mode in such cases.
